module MediaWiktory::Wikipedia
  module Modules
    # Perform a full text search.
    #
    # The "submodule" (MediaWiki API term) is included in action after setting some param, providing
    # additional tweaking for this param. Example (for {MediaWiktory::Wikipedia::Actions::Query} and
    # its submodules):
    #
    # ```ruby
    # api.query             # returns Actions::Query
    #    .prop(:revisions)  # adds prop=revisions to action URL, and includes Modules::Revisions into action
    #    .limit(10)         # method of Modules::Revisions, adds rvlimit=10 to URL
    # ```
    #
    # All submodule's parameters are documented as its public methods, see below.
