title: How can I implement a text search in node.js using a Postgres database?
body: <p>I want to add search functionality to an expressjs node application using Postgres as my database.
  I know how to do the filtering I'll need by date and some other column of finite values, but I don't know how to do a text search on a specific column. 
  Given a string "chair", should my search algorithm return results with text like "my armchair", or "my chair"?</p>
  
  <p>Maybe this question is so simple I'm just overlooking something.
  Thanks!</p>
