__call__()

searx.query.LanguageParser.__call__	(		self,
			raw_value )

Try to parse raw_value: set the self.raw_text_query properties

return True if raw_value has been parsed

self.raw_text_query.autocomplete_list is also modified
if self.enable_autocomplete is True

Reimplemented from searx.query.QueryPartParser.
