i need help on building search engine that can integrate information from other search engine.please help me...

pcthug

Whom is the other search engine? Do you have access to this search engine's database, etc?

harita_hadraw

that is the problem...i need to integrate data from citeseer n obviously...i dont have the access to its database..can u help me?i need to make it like google...search into other search engine, merge the results.

pcthug

When you speak of citeseer, are you referring to The scientific literature digital library?

harita_hadraw

yes...u r correct.that citeseer.can u help me?to retrieve the data from citeseer?

pcthug

As the site uses the GET method of data encoding you could pass your query as
http://citeseer.ist.psu.edu/cis?q=<query>
include various other parameters (i.e. cs=). Then you would read the dynamically created page, focusing and extracting the results. This extracting process would simply read all results into a local format which you could then redisplay and reformat yourself.
Please note: Such replication may infringe certain copyright laws and therefore should not be practiced without strict permission from the site owner or collectively Citeseer.

sorry..i didnt get that.i mean...where to put the "http://citeseer.ist.psu.edu/cis?q=<query>" in my codes?im really stuck here

harita_hadraw

what is cs stands for?is it really just like that?ive try everything,but still cannot send my query to citeseer.

pcthug

Ok, firstly: What (if any) server-side technologies (PHP, ASP, JAVA, CGI-PERL, ColdFusion, etc.) do you have available to you?

harita_hadraw

im using php..

pcthug

Try this little php script:

<?php

if(!isset($_GET['q']) || empty($_GET['q']))
{
	echo <<<form
<form action="{$_SERVER['REQUEST_URI']}" method="get">
<input type="text" name="q">
<input type="submit" name="submit" value="Search">
</form>
form;
}

else
{
	echo readfile("http://citeseer.ist.psu.edu/cis?q={$_GET['q']}");
}

?>

harita_hadraw

while implementing this scripts,an error occured on line 5 (echo <<<form ) and line 10(form).y?n how to solve it?

harita_hadraw

the form tag cannot be inside the php scripts..how 2 solve this?

pcthug

For such an error to be trigged I am led to believe that you do not have Heredoc syntax support ad therefore are running on an ancient version of PHP (like < version 4), try this script instead:

<?php

if(!isset($_GET['q']) || empty($_GET['q']))
{	
	$self = $HTTP_GET_VARS['PHP_SELF'];
   echo "<form action=\"$self\" method=\"get\">\n<input type=\"text\" name=\"q\">\n<input type=\"submit\" name=\"submit\" value=\"Search\">\n</form>\n";
}

else
{
    $q = $HTTP_GET_VARS['q'];
    echo readfile("http://citeseer.ist.psu.edu/cis?q=$q");
}

?>

harita_hadraw

new problem exists

Warning: readfile("http://citeseer.ist.psu.edu/cis?q=information integration") - No error in c:\apache\htdocs\cari.php on line 12

Fatal error: Maximum execution time of 30 seconds exceeded in c:\apache\htdocs\cari.php on line 12

harita_hadraw

i know now why the problem exists.it is because there's a space between the keywords, such as "information integration".it can onlys earch for one words not many words coz it cant read space.how to overcome this?

pcthug

Try:

<?php

if(!isset($_GET['q']) || empty($_GET['q']))
{
   echo "<form action=\"{$_SERVER['PHP_SELF']}\" method=\"get\">\n<input type=\"text\" name=\"q\">\n<input type=\"submit\" name=\"submit\" value=\"Search\">\n</form>\n";
}

else
{
    $q = str_replace(' ', '+', $_GET['q']);
    echo readfile("http://citeseer.ist.psu.edu/cis?q=$q");
}

?>
