title: Algolia per session index settings?
body: <p>I have a collection where I'm allowing users to add or remove fields through a configuration and would like to index and search that collection with Algolia. </p>
  
  <p>To do this I'm doing is calling <code>setStettings</code> on my index with the user-specific <code>searchableAttributes</code>, <code>numericAttributesForFiltering</code>, and <code>attributesForFaceting</code> when they log in. </p>
  
  <p>This seems to work in testing, but I'm not really sure what I'm doing with that call. Is that <code>setSettings</code> call specifying the settings for that instance of the index, only affecting subsequent <code>search</code> calls in that session? Or is it resetting the index settings in Algolia itself, affecting all users?</p>
  
  <p>Thanks.</p>
