Hi, I am new to Lucene and this mailing list, so my apologies if these questions have already been answered.
1) I create an index with one document with a searchable field of "All dogs are brown." If I search on that index with a query of "All dogs are brown." I do not get a hit with score 1.0, but something low like 0.38. I tried looking at the scoring algorithm and can't make heads or tails of it. Can anybody explain it to me in simple terms? 2) I have an index of documents, then run a search against it. I run through the list of hits, building a Vector of documents whose score is above a certain threshold. If I run the program with a threshold of say, 0.15, I'll get a Vector of documents with scores >= 0.15 (as expected). If I set the threshold higher (0.30, for example) and rerun the program, I see some of the same documents that I thought would have been trimmed off with the higher threshold. With a threshold of 0.15 they would score 0.17, and with a threshold of 0.30 they are scoring something like 0.33. Can anybody explain this? My trimming is coming post-index-searching, so this is pretty confusing. Thanks in advance for any help.
