-- Gets the analysis schemes configured for a domain. An analysis scheme
-- defines language-specific text processing options for a 'text' field.
-- Can be limited to specific analysis schemes by name. By default, shows
-- all analysis schemes and includes any pending changes to the
-- configuration. Set the 'Deployed' option to 'true' to show the active
-- configuration and exclude pending changes. For more information, see
