Description
Add support for the
case_insensitiveparameter for some elasticsearch DSL queries:To support case insensitive search on regex based ASTs a mode modifier
(?i), is added at the beginning of the regex string.For term queries this PR fallback to using a
RegexQueryAST whencase_insensitiveis set to True.It seems that elasticsearch uses a case insensitive Lucene automaton to cover this case.
