This is an ancient problem. The issue here is your mm-parameter, it gets confused because for separate fields different amount of tokens are filtered/emitted so it is never going to work just like this. The easiest option is not to use the stopfilter.

Fair enough, I have stopword "and" in the query > analyser chain. > > However, I also need to support French as well as English, so I've got _en > and _fr versions of the text fields, with appropriate stemming and > stopwords. I index French content into the _fr fields and English into the > _en fields. I'm searching with eDisMax over both versions, e.g.: > > <str name="qf">headline_en headline_fr</str> > > However, this means I get no results for "oscar and wilde". The parsed > query is: > > (+((DisjunctionMaxQuery((headline_fr:osca | headline_en:oscar)) > DisjunctionMaxQuery((headline_fr:and)) > DisjunctionMaxQuery((headline_fr:wild | headline_en:wild)))~3))/no_coord > > If I add "and" to the French stopwords list, I *do* get results, and the > parsed query is: > > (+((DisjunctionMaxQuery((headline_fr:osca | headline_en:oscar)) > DisjunctionMaxQuery((headline_fr:wild | headline_en:wild)))~2))/no_coord > > This implies that the only solution is to have a minimal, shared stopwords > list for all languages I want to support. Is this correct, or is there a > way of supporting this kind of searching with per-language stopword lists? > > Thanks for any ideas! > > Tom >
