Search Engine

[atholon]

Hey,

 

I want to make a search engine that singles out the individual keywords entered into the search and then also uses various synonyms for that word.

 

Can anyone let me know where I can find a listing for that if there is one for free?

Doubt you'd get one for free that'd be any good.. you'll need to look into creating a crawler / spider.. you'll find millions of results on google..

Creating that by yourself would need some knowledge, so thats out of reach. Maybe u can use google custom search??

It wouldn`t be that complicated if I could find a list of words and their synonyms which I doubt can be found for free. I am just checking to make sure

 

It would make the search engine much more accurate.

U couldnt need a list of words, u would need a complete english thesaurus.

ive acctually got a code which will use googles feature for that it runs a search through google and then if google  says it is spelt wrong this code will get what comes after Did you mean: and return that value

heres the function if you want it:

 

<?php
function DidYouMean($search){
$content = file_get_contents('http://www.google.com/search?q='.str_replace(' ', '+', $search).'');
preg_match('#<div id=res>(.*?)<div>#', $content, $matches);
$match = str_replace('    Did you mean: ', '', str_replace('  ', '', strip_tags($matches[1])));	
if($match == '' || $match == '    '){
	return 'none';
}else{
  return $match;
}
}

$result = DidYouMean($_GET['q']);

if($result == 'none'){
echo 'You spelt that query correct!';
}else{
echo 'We didn\'t find any results for "'.$_GET['q'].'", did you mean <strong>'.$result.'</strong>?';
}
?>
