  class User

include Mongoid::Document

The second parameter of exist has to be an string, and the quote has to be escaped as ''.

For example, where not exist(data, '''a''')

example_db=# create table something (id serial primary key, data hstore);

We create an index with:

two filters: synonyms_expand and synonyms_contract
two analyzers: synonyms_expand and synonyms_contract
three text fields:
- text_1 uses the synonyms_expand analyzer at index and search time
- text_2 uses the synonyms_expand analyzer at index time, but the standard analyzer at search time
- text_3 uses the synonyms_contract analyzer at index and search time
