title: SQL query'ish for what I want to achieve in Pouchdb
body: <pre><code>SELECT * FROM smo_images
  WHERE search_term in search_helpers (search helpers is array or keywords)
  OR search_term = smo_code
  OR search_term = size
  OR search_term = category;
  </code></pre>
  
  <p>I would like to achieve something like above in PouchDB. I am new to nosql and PouchDB. The documentation is confusing and not straightforward. </p>
