Zammad installation without elasticsearch

Hi All,

Is it possible to running zammad without elasticsearch?
I have been running zammad with elasticsearch, but i have a problem with Elasticsearch instance, it need big resources..

The other problem is we need to reindex Elasticsearch after:

  1. add new field on object
  2. Delay when search after adding new user or group.
    rake zammad:searchindex:rebuild
    it takes an hour, depends the documents count.

so i think if we are disabling it, how is it going?
