Hi folks, I have a query result problem I do not understand. The documentation for Lucene 3.2 query syntax says the following about boolean OR queries: "The OR operator links two terms and finds a matching document if either of the terms exist in a document. This is equivalent to a union using sets."
I have performed several queries on my index and the output does not reflect the description. I always get the first-wins-set instead of a united set. These are my separate test results: 1. schluessel:23????? => 286 documents 2. vorgklasse:au AND schluessel:13????? => 2532 documents If I do: vorgklasse:au AND schluessel:13????? OR schluessel:23????? It should unite both sets and output them. I still get 2532 documents back. Exactly those from the second query. Am I not supposed to get 2532 + 286 = 2818? This is what I expect as result set. Am I missing something here? If I group the query like this (vorgklasse:au AND sch luessel:13?????) OR schluessel:23????? I do get the expected result. But both queries should be equivalent. Thanks, Mike PS: search output is avaible as CSV at request -- NEU: FreePhone - 0ct/min Handyspartarif mit Geld-zurück-Garantie!
