<script type="text/x-red" data-help-name="mongodb out">
    <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 <code>msg</code> 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>. If <code>msg.query._id</code> is
    a valid mongo ObjectId string it will be converted to an ObjectId type.</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.

    fields, a <code>msg.sort</code> object, a <code>msg.limit</code> number and a <code>msg.skip</code> number.</p>
    <p>Count returns a count of the number of documents in a collection or matching a query using the

    <p>Aggregate provides access to the aggregation pipeline using the <code>msg.payload</code> as the pipeline array.</p>
