#search(query) ⇒ Set

TODO:

Rename to #load_set

Note:

This method is optimized for fast lookups by name, i.e. it does not require iterating through #pod_sets

Returns a set for a given dependency. The set is identified by the name of the dependency and takes into account subspecs.

Returns:

  • (Set) —

    a set for a given dependency. The set is identified by the name of the dependency and takes into account subspecs.

    set if set.specification_name == query
  end
end

#search_by_name(query, full_text_search = false) ⇒ Array<Set>

Note:

full text search requires to load the specification for each pod, and therefore not supported.

Returns The list of the sets that contain the search term.

Parameters:

  • query (String) —

    the search term. Can be a regular expression.

  • full_text_search (Boolean) (defaults to: false) —

    performed using Algolia

Returns:

  • (Array<Set>) —

    The list of the sets that contain the search term.
