its really just a bad situation for chinese :( with queryparser, you either get no phrase query support (by using the hack), or all queries automatically become phrase queries.
if you want to do the equivalent of *在电力虎*, then you need to use queryparser without the hack, just do a query of "在电力虎" (with quotes). if you want to do the equivalent of 在 电 力 虎, then you need to use queryparser with the hack, just do a query of 在电力虎 (without quotes). 2010/7/1 Kolhoff, Jacqueline - ENCOWAY <kolh...@encoway.de> > Ok, understand! > > So it is better to use another analyzer in the chinese case at index-time > or do you suggest to use another "QueryParser" at query-time? > > -----Ursprüngliche Nachricht----- > Von: Robert Muir [mailto:rcm...@gmail.com] > Gesendet: Donnerstag, 1.
