Instance Method Details

#search_result_ranks_and_ids(tokens, user = User.current, projects = nil, options = {}) ⇒ Object

Searches the model for the given tokens and user visibility. The projects argument can be either nil (will search all projects), a project or an array of projects. Returns an array that contains the rank and id of all results. In current implementation, the rank is the record timestamp converted as an integer.

Valid options:

  • :titles_only - searches tokens in the first searchable column only

  • :all_words - searches results that match all token

  • :

  • :limit - maximum number of results to return

Example:

Issue.search_result_ranks_and_ids("foo")
# => [[1419595329, 69], [1419595622, 123]]
