    <p>A simple MongoDB output node. Can save, insert, update and remove objects from a chosen collection.</p>
    <p>Save will update an existing object or insert a new object if one does not already exist.</p>
    <p>Insert will insert a new object.</p>
    <p>Save and insert either store <b>msg</b> or <code>msg.payload</code>.</p>
    <p>Update will modify an existing object or objects. The query to select objects to update uses <code>msg.query</code> and the update to the element uses <code>msg.payload</code>.</p>
    <p>Update can add a object if it does not exist or update multiple objects.</p>
    <p>Remove will remove objects that match the query passed in on <code>msg.payload</code>. A blank query will delete <i>all of the objects</i> in the collection.</p>
    <p>You can either set the collection method in the node config or on <code>msg.collection</code>. Setting it in the node will override <code>msg.collection</code>.</p>
    <p>By default MongoDB creates an <i>_id</i> property as the primary key - so repeated injections of the same <code>msg</code> will result in many database entries.</p>
    <p>If this is NOT the desired behaviour - ie. you want repeated entries to overwrite, then you must set the <code>msg._id</code> property to be a constant by the use of a previous function node.</p>
    <p>This could be a unique constant or you could create one based on some other msg property.</p>
    <p>Currently we do not limit or cap the collection size at all... this may well change.</p>

    <p>Calls a MongoDB collection method based on the selected operator.</p>
    <p>Find queries a collection using the <code>msg.payload</code> as the query statement as per the .find() function.
    Optionally, you may also (via a function) set a <code>msg.projection</code> object to constrain the returned fields,
    a <code>msg.sort</code> object and a <code>msg.limit</code> object.</p>
    <p>Count returns a count of the number of documents in a collection or matching a query using the <code>msg.payload</code> 
    as the query statement.</p>
    <p>Aggregate provides access to the aggregation pipeline using the <code>msg.payload</code> as the pipeline array.</p>

    collection methods docs</i></a> for examples.</p>
