Carrot2 dcs error 500

I've installed Carrot2 on a web application. I send a search with differents options like : number of expected results, depth level. I launch dcs (port 8080) and execute my search (for the moment i'm using wamp on localhost). I init a new Carro2Processor with baseurl : http://localhost:8080/dcs/rest

$source = 'etools';
$query = 'myquery';
$algorithm = 'lingo3g';
$processor = new Carrot2Processor();
$job = new Carrot2Job();
$job->setSource($source);
$job->setQuery($query);
$job->setAlgorithm($algorithm);

I send my attributs with setAttributs() :number of expected results and depth level

try {
    $result = $processor->cluster($job);
}

This is my error on my browser :

C:\wamp64\www\lingo3g-php-search\model\Carrot2.php:239:string '<html>

Has anyone encountered this problem ? Thanks (I forgot : I don't have any error log in my apache or php(wamp))

Solution

  • It appears that the recent release renamed the etools document source to web without updating code examples. If you change $source = 'etools' to $source = 'web', you should see some results.
