Is this gem supporting multiple models? I guess the gem supports 1 model at the same time.
Do you have a plan for supporting multiple models?

I'm having a hard time understanding what to pass into .search and .query. It would be great to document the options hash that .search takes in. If you flesh out some of the documentation, I would be more than willing to contribute some more in the same pattern!

Currently, support one instance.

Description

• When using ActiveRecord data accessor or Mongoid data accessor
• and pass options to search and call execute causes undefined method error like following.
• This error can be reproduce by the steps which is explained later.

     NoMethodError:
       undefined method `in' for nil:NilClass
     # ./lib/nazrin/data_accessor/mongoid.rb:10:in `block in load_all'
     # ./lib/nazrin/data_accessor/mongoid.rb:6:in `each'
     # ./lib/nazrin/data_accessor/mongoid.rb:6:in `load_all'
     # ./lib/nazrin/data_accessor.rb:64:in `results'
     # ./lib/nazrin/search_client.rb:122:in `execute'
     # ./spec/nazrin/data_accessor/mongoid_spec.rb:27:in `block (4 levels) in <top (required)>'

The error occurs here .

In this code, right side model is not the method of DataAccessor but nil, because by executing model = , model is defined as a new local variable. So we failed to call methods.

Environment

• ruby 2.5.3
• nazrin 2.6.1
• with rails 5.2.0 or mongoid 7.0.2

How to reproduce
