MongoDB query $in with regex array of element : <p>Ok i am trying to implement a query, which is trying to perform regex search ( which contains an array list ) on a bunch of document</p>

<p>Its hard for me to explain...so I am basically coming to direct point.</p>

<p>There is query which works with regex array...</p>

<pre><code>db.paper.find({"category": {$in: [ /xd/, /sd/, /ad/ ] }})
</code></pre>

<p>There is query which doesn't works with regex array...</p>

<pre><code>db.paper.find({"category": {$in: [ "/xd/", "/sd/", "/ad/" ] }})
</code></pre>

<p>So basically what I want is remove "" sign from string array...so that i can perform below query..</p>

<pre><code>var sea = [ "/xd/", "/sd/", "/ad/" ];
db.paper.find({"category": {$in: sea }});
</code></pre>
