title: How to embed a field from one database to another
body: <p>I have two collections (<code>_items</code> and <code>_details</code>), and within the <code>_details</code> database I have a field called <code>product_description</code>, how would I be able to embed that field to the <code>_items</code> database by matching the <code>product_barcode</code> field as both of the databases have that field. I am trying to get the descriptions to match the barcodes in the <code>_items</code> database</p>
  
  <p>Any help would be appreciated</p>
