[basex-talk] Question about the Fulltext search!

Hi, I've two questions about the fulltext search. 1) I've created fulltext i for my BaseX doesn't understand ftcontains. When I try a CONTAINS query in a 1 Gigabyte Database, using text index is slower than without text index. How can I use fulltext index rightly? 2) Does BaseX supports regular expression in the fulltext extension? If yes, could you please give me an example. Thanks Cheers, An
