title: Fulltext Search DynamoDB
body: <p>Following situation: </p>
  
  <p>I´m storing elements in a DyanmoDb for my customers. HashKey is a Element ID and Range Key is the customer ID. In addition to these fields I´m storing an array of strings -> tags (e.g. ["Pets", "House"]) and a multiline text.</p>
  
  <p>I want to provide a search function in my application, where the user can type a free text or select tags and get all related elements.</p>
  
  <p>In my opinion a plain DB query is not the correct solution. I was playing around with CloudSearch, but I´m not really sure if this is the correct solution, because everytime the user adds a tag the index must be updated...</p>
  
  <p>I hope you have some hints for me.</p>
