Secret 1:- Syntax Search
Using a special syntax is a way to tell Google that you want to restrict your searches to certain elements or characteristics of Web pages. Google has a fairly complete list of its syntax elements at www.google.com/help/operators.html. Here are some advanced operators that can help narrow down your search results.
Intitle: at the beginning of a query word or phrase (intitle:”Three Blind Mice”) restricts your search results to just the titles of Web pages.
Intext: does the opposite of intitle:, searching only the body text, ignoring titles, links, and so forth. Intext: is perfect when what you’re searching for might commonly appear in URLs. If you’re looking for the term HTML, for example, and you don’t want to get results such as www.mysite.com/index.html, you can enter intext:html.
Link: lets you see which pages are linking to your Web page or to another page you’re interested in. For example, try typing in link:http://www.2tech.net
Try using site: (which restricts results to top-level domains) with intitle: to find certain types of pages. For example, get scholarly pages about Mark Twain by searching for intitle:”Mark Twain”site:edu. Experiment with mixing various elements; you’ll develop several strategies for finding the stuff you want more effectively. The site: command is very helpful as an alternative to the mediocre search engines built into many sites.
Secret 2:- Hidden Services
Google has a number of services that can help you accomplish tasks you may never have thought to use Google for. For example, the new calculator feature (www.google.com/help/features.html#calculator) lets you do both math and a variety of conversions from the search box. For extra fun, try the query “Answer to life the universe and everything.”
Let Google help you figure out whether you’ve got the right spelling—and the right word—for your search. Enter a misspelled word or phrase into the query box (try “thre blund mise”) and Google may suggest a proper spelling. This doesn’t always succeed; it works best when the word you’re searching for can be found in a dictionary. Once you search for a properly spelled word, look at the results page, which repeats your query. (If you’re searching for “three blind mice,” underneath the search window will appear a statement such as Searched the web for “three blind mice.”) You’ll discover that you can click on each word in your search phrase and get a definition from a dictionary.
Suppose you want to contact someone and don’t have his phone number handy. Google can help you with that, too. Just enter a name, city, and state. (The city is optional, but you must enter a state.) If a phone number matches the listing, you’ll see it at the top of the search results along with a map link to the address. If you’d rather restrict your results, use rphonebook: for residential listings or bphonebook: for business listings. If you’d rather use a search form for business phone listings, try Yellow Search (www.buzztoolbox.com/google/yellowsearch.shtml).
Secret 3:- Extreme Googling
Google offers several services that give you a head start in focusing your search. Google Groups (http://groups.google.com) indexes literally millions of messages from decades of discussion on Usenet. Google even helps you with your shopping via two tools: Froogle (http://froogle.google.com), which indexes products from online stores, and Google Catalogs (http://catalogs.google.com), which features products from more 6,000 paper catalogs in a searchable index. And this only scratches the surface. You can get a complete list of Google’s tools and services at www.google.com/options/index.html.
You’re probably used to using Google in your browser. But have you ever thought of using Google outside your browser?
Google Alert (www.googlealert.com) monitors your search terms and e-mails you information about new additions to Google’s Web index. (Google Alert is not affiliated with Google; it uses Google’s Web services API to perform its searches.) If you’re more interested in news stories than general Web content, check out the beta version of Google News Alerts (www.google.com/newsalerts). This service (which is affiliated with Google) will monitor up to 50 news queries per e-mail address and send you information about news stories that match your query. (Hint: Use the intitle: and source: syntax elements with Google News to limit the number of alerts you get.)
Google on the telephone? Yup. This service is brought to you by the folks at Google Labs (http://labs.google.com), a place for experimental Google ideas and features (which may come and go, so what’s there at this writing might not be there when you decide to check it out). With Google Voice Search (http://labs1.google.com/gvs.html), you dial the Voice Search phone number, speak your keywords, and then click on the indicated link. Every time you say a new search term, the results page will refresh with your new query (you must have JavaScript enabled for this to work). Remember, this service is still in an experimental phase, so don’t expect 100 percent success.
In 2002, Google released the Google API (application programming interface), a way for programmers to access Google’s search engine results without violating the Google Terms of Service. A lot of people have created useful (and occasionally not-so-useful but interesting) applications not available from Google itself, such as Google Alert. For many applications, you’ll need an API key, which is available free from www.google.com/apis.
Thanks to its many different search properties, Google goes far beyond a regular search engine. Give the tricks in this article a try. You’ll be amazed at how many different ways Google can improve your Internet searching.
Secret 4:- Search Between Date Range
Daterange: (start date–end date). You can restrict your searches to pages that were indexed within a certain time period. Daterange: searches by when Google indexed a page, not when the page itself was created. This operator can help you ensure that results will have fresh content (by using recent dates), or you can use it to avoid a topic’s current-news blizzard and concentrate only on older results. Daterange: is actually more useful if you go elsewhere to take advantage of it, because daterange: requires Julian dates, not standard Gregorian dates. You can find converters on the Web (such as http://aa.usno.navy.mil/data/docs/JulianDate.html), but an easier way is to do a Google daterange: search by filling in a form at www.researchbuzz.com/toolbox/goofresh.shtml or www.faganfinder.com/engines/google.shtml. If one special syntax element is good, two must be better, right? Sometimes. Though some operators can’t be mixed (you can’t use the link: operator with anything else) many can be, quickly narrowing your results to a less overwhelming number.

| In this article, we will discuss how to use Microsoft ASP technology to handle user-submitted form data and then send that data to someone via email with Microsoft’s Collaboration Data Object for NT Server (CDONTS). |
Introduction
Microsoft’s Active Server Page technology is a powerful server-side scripting method of web development that allows any web developer with a web server powered by NT’s Internet Information Services (IIS) and a basic understanding of HTML and VBScript to create powerful dynamic web pages.
This article assumes that you have the basic HTML and VBScript understanding mentioned above. However, I will explain anything that is crucial to your understanding.
If you have ever created or thought about creating an HTML form for user input on your web site, then you must have also dealt with the issue of handling the data once it is submitted (ie. where does the data go and how does it get there). As you may already know, if you want the information submitted to be emailed to you, you can simply put your email address in the action field of the FORM tag like this:
<form action="mailto:corinth@enfused.com" method="get" enctype="text/plain">
TIP: If you do not have time or the resources to program an ASP page or Perl script to handle your form’s submitted data, you can use a little-known HTML trick to make the submitted form data reach your inbox in a legible fashion. By adding enctype="text/plain" to your form tag, the output will come across as standard plain text rather than that garbled mess that normally comes across when you set the action equal to mailto:some_email@address.com. |
However, you probably also know that when you use the mailto action, your users will get an obnoxious and frightening security warning, and we do not want to scare your users away!
To avoid the security alert, you have a couple of options. First, if you are developing in a UNIX environment, using Perl and CGI would probably be your best bet. .
On the other hand, if you are developing in an NT environment, while you may still use Perl and CGI if Perl is installed on your server, it is recommended that you use ASP because it is easier to code and a bit more intuitive, for novices and experts alike.
In the remainder of this article, I will show you how to use ASP to handle the form data and then send it to an email address using the Collaborative Data Object for NTS (CDONTS), a special Windows NT COM object designed to send mail through the SMTP service on your web server.
Learn how to create and handle Web-based forms using ASP.
Forms collect data from the user and post it back to the server for processing. They feature in guest books, feedback pages, shopping carts, search engines, and almost all interactive websites. In this tutorial, we’ll show you how you can use ASP to get at the data that’s sent to the web server from a form.
All HTML forms are created using the form element:
<form method="xxxx" action="xxxx"> (form fields in here) </form>The method attribute controls how the information that the user enters in the form is sent to the server. The two options are:
GET
Sends the form data as part of the URL (e.g. "script.pl?& email=joe@joe.com"). This is the default option. It’s useful and efficient for small amounts of data (e.g. a search engine query) and it’s easy for the user to refresh the results of the form by just pressing the browser’s refresh button. However it cannot be used for large amounts of data (more than a few hundred bytes).
POST
Sends the form data encoded in the HTTP data stream. This is recommended for most types of forms (e.g. feedback forms and form mailers). The user will not see the form data in the URL. Large amounts of data can be sent this way. Unlike the GET method, the user cannot easily refresh the form results page – they usually see a dialog asking if they want to resend the form data – but this is often a good thing!
The action attribute specifies where the form data submitted by the user will be sent. Usually this is the URL of a script on the server – for example, http://www.yoursite.com/feedback.asp or http://www.yoursite.com/poll.asp.
If you’re thinking you recognise this part of the tutorial, that’s because it’s part of the ELATED HTML Forms tutorial. If you need any help on creating form fields, you might like to check out that tutorial.
Request.QuerystringWe use the Request.Querystring collection to retrieve data posted from forms that use the GET method. The collection contains an entry for each form field posted to the server. Assume we have an HTML form as follows:
<form method="get" action="querystring.asp"> Title: <select> <option value="Mr">Mr.</option> <option value="Miss">Miss</option> <option value="Ms">Ms.</option> <option value="Mrs">Mrs.</option> </select><br> First name: <input><br> City: <input><br> <input value="Send"></form>We could use
Request.Querystring("title")Request.Querystring("firstname")Request.Querystring("city")to retrieve the values entered by the user. There would be a named entry for each named form field, so the “submit” button would also result in a value being stored in Request.Querystring("submit").
Request.FormASP provides the Request.Form collection to retrieve data sent from forms using the POST method. As with the QueryString collection, the Form collection also contains an entry for each form field posted to the server. So, taking our example form above and changing the GET method to be a POST, we could use:
Request.Form("title")Request.Form("firstname")Request.Form("city")Request.Form("submit")to retrieve the values entered by the user. Sometimes you’ll see ASP code where Request.QueryString("field_name") or Request.Form("field_name") has been written as Request("field_name"). This is a valid short-hand notation, however it is usually a good idea to explicitly reference the collection you want to use – it’s faster to execute and it avoids ambiguity where an item in a different collection might have the same name.
Sometimes we might have a form that contains a set of checkboxes. If we make these a group by giving them the same name, all the checked box values will be sent to the server using the same field name:
<form method="post" action="checkbox.asp"> Please check the boxes to indicate your interests:<br> <input value="film"> Film<br> <input value="music"> Music<br> <input value="theatre"> Theatre<br> <input value="sports"> Sports<br> <input value="Send"></form>Assume we checked all four boxes, we can access the values like this:
Request.Form("interests")(1)Request.Form("interests")(2)Request.Form("interests")(3)Request.Form("interests")(4)We can also use the Count property to find out how many values were submitted. (In the above example, Request.Form("interests").Count equals 4.) This allows us to loop through the values using a For ... Next loop:
For counter = 1 To Request.Form("interests").Count Response.Write "You selected " & Request.Form("interests")(counter) & "<br>"Next(If you’re not familiar with loops, you might want to read our loops tutorial.) However, usually we’d want to use code like this to retrieve the data:
For Each item In Request.Form("interests") Response.Write "You selected " & item & "<br>"NextThis loops through each of the values submitted one at a time and outputs each one. Unlike the previous For counter = 1 To Request.Form("interests").Count ... Next loop, the example above will work even when no checkboxes were selected.
In this tutorial, we’ve learnt how to access form data using ASP. This is a key skill that you’ll use time and again when creating websites. To make the most of forms, you’ll probably want to either store the data, or email the data to someone. We’ll show you how to do these in future ELATED tutorials
