如何在mongodb中使用php搜索全文索引

Question

I'm using mongodb 2.4 and added fulltext index to the "title" field in one the collection. How should I search something in that field using php?

This is the code I use right now:

$params = array(
        '_id' => array(
            '$gt' => (int)$gt
        )
    );
$r = $this->collection->find( $params )->limit($limit);

Answer 1

This seem to be the answer to my question:

<?php
$result = $db->command(
    array(
        'text' => 'bar', //this is the name of the collection where we are searching
        'search' => 'hotel', //the string to search
        'limit' => 5, //the number of results, by default is 1000
        'project' => Array( //the fields to retrieve from db
            'title' => 1
        )
    )
);
