title: PostgreSQL Full Text search
body: <p>I need to use Full Text Search with Postgresql but I don't find the way to look for a list of words from a table (using <code>ts_query</code>) against an indexed text field (<code>ts_vector</code> data type). Is <code>ts_query</code> just able to process a few words or can process also multiple values that come from a table?</p>
  
  <p>Thanks in advance for your help. </p>
