<p>Find queries a collection using the <b>msg.payload</b> as the query statement as per the .find() function. Optionally, you may also (via a function) set a <b>msg.projection</b> object to constrain the returned fields, a <b>msg.sort</b> object and a <b>msg.limit</b> object.</p>
<p>Count returns a count of the number of documents in a collection or matching a query using the <b>msg.payload</b> as the query statement.</p>
<p>Aggregate provides access to the aggregation pipeline using the <b>msg.payload</b> as the pipeline array.</p>
<p>You can override the collection the method is performed on by setting <b>msg.collection</b> to the desired collection name.</p>
<p>You can either set the collection method in the node config or on <b>msg.collection</b>. Setting it in the node will override <b>msg.collection</b>.</p>
<p>See the <a href="http://docs.mongodb.org/manual/reference/method/db.collection.find/" target="new"><i>MongoDB collection methods docs</i></a> for examples.</p>
