@pcthugAug 01.2006 — #Whom is the [I]other search engine[/I]? Do you have access to this search engine's database, etc?

@harita_hadrawauthorAug 01.2006 — #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.

@pcthugAug 01.2006 — #When you speak of [I]citeseer[/I], are you referring to [url=http://citeseer.ist.psu.edu]The scientific literature digital library[/url]?

@harita_hadrawauthorAug 01.2006 — #yes...u r correct.that citeseer.can u help me?to retrieve the data from citeseer?

@pcthugAug 01.2006 — #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.

@harita_hadrawauthorAug 01.2006 — #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_hadrawauthorAug 01.2006 — #what is cs stands for?is it really just like that?ive try everything,but still cannot send my query to citeseer.

@pcthugAug 01.2006 — #Ok, firstly: What (if any) server-side technologies (PHP, ASP, JAVA, CGI-PERL, ColdFusion, etc.) do you have available to you?

@harita_hadrawauthorAug 01.2006 — #im using php..

@pcthugAug 01.2006 — #Try this little php script:

[code=php]
 <?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']}");
 }
 
 ?>
 [/code]

@harita_hadrawauthorAug 01.2006 — #while implementing this scripts,an error occured on line 5 (echo <<<form ) and line 10(form).y?n how to solve it?

@harita_hadrawauthorAug 01.2006 — #the form tag cannot be inside the php scripts..how 2 solve this?

@pcthugAug 01.2006 — #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:

[code=php]
 <?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");
 }
 
 ?> [/code]

@harita_hadrawauthorAug 01.2006 — #new problem exists

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

Fatal error: Maximum execution time of 30 seconds exceeded in c:apachehtdocscari.php on line 12

@harita_hadrawauthorAug 02.2006 — #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?

@pcthugAug 02.2006 — #Try:

[code=php]
 <?php
 
 if(!isset($_GET['q']) || empty($_GET['q']))

@harita_hadrawauthorAug 04.2006 — #perhaps the readfile code?

@pcthugAug 04.2006 — #So where would you like the citeseer results to appear? Under your database results, above? If so, what is the use of $choice1? Please Explain.

@harita_hadrawauthorAug 06.2006 — #there is 2 radio button.1 is to search from my database only(its easy n its done).the 2nd is search to citeseer n my database together,then combine the results(form search to citeseer n my database) rank it n then display the result.how to do it then?can u help me?

[B]for the cosrep n cieseer radio button...it should be able to search to my own database n citeseer,rank the results n display it..how to do it?[/B]

@pcthugAug 06.2006 — #To rank the results some type of algorithm must be used, this algorithm could easily be used with just your results - however when combining 2 sets of results (one of which we can't access directly) accurate ranking becomes near impossible.

@harita_hadrawauthorAug 06.2006 — #if i cant rank the result,at least i could combine the search result.thats all i need to do for now.can u help me?maybe,i could retrieve the result from citeseer and save it to my database or something.for at least i could combine the search result.

@pcthugAug 06.2006 — #What is the value of $hit:

[code=php]
 echo "<td width=100%><a target='_blank' href=$row[url1]><u>$row[title]</u></a></td><td width=20%>$hit</td>";[/code]

@pcthugAug 06.2006 — #And $row['abstract'] and $row['publishon']?
[code=php]echo "<td width=100%>$row[abstract]</td><td width=20%>$row[publishon]</td></tr>";[/code]
The reason I ask is because I'm trying to format the citeseer results the same as your database results and i'm not sure where to get this information from.
