Hi Christoph, There could be several things going on, but it's difficult to tell without more information.
Since excluded terms require a non-empty set from which to remove documents at the same boolean clause level, you could try something like "title:(*:* -Datei*) avl", or "-title:Datei* avl". Another possible problem is case. If you downcase indexed terms, "Datei*" will not match any of them by default, since no analysis is carried out on wildcard terms. QueryParser has a static method setLowercaseExpandedTerms() that you can call to turn on automatic pre-expansion query term downcasing: <http://lucene.apache.org/java/3_0_2/api/all/org/apache/lucene/queryParser/QueryParser.html#setLowercaseExpandedTerms%28boolean%29> Steve > -----Original Message----- > From: Christoph Hermann [mailto:herm...@informatik.uni-freiburg.de] > Sent: Monday, August 16, 2010 9:32 AM > To: java-user@lucene.apache.org > Subject: Search results include results with excluded terms > > Hi, > > i've built a local index of the german wikipedia (works fine so far). > > Now when i'm searching this index with luke (or my own code) using a query > like "title:(-Datei*) avl" i still get results with Documents where the > title contains: "Datei:foo". > > The title field is created like this: > Field fieldTitle = new Field(Metadata.TITLE, title, Field.Store.YES, > Field.Index.ANALYZED); > > Can someone explain to me why i still get these results? > > If i click on "explain" in luke, it tells me that the score basically came > from the contents field where "avl" is included. > > So the question is, how do i *exclude* documents?
