Re: MoreLikeThis function queries

: Are function queries possible using the MLT request handler? How about using : the _val_ hack? Thanks for your help Did you try it? The MoreLikeThisHandler uses the same parsing logic to build it's initial query as the SearchHandler, so you can use whatever parsers you want (including the "{
