Re: Concurrent Issue

Building on Aditya's comments. 1. Lucene in Action has a SearchManager class which does most of 1-5 and manages indexreaders. 2. Reference counting is not the best approach, it is too low level and error prone. Instead Use ReadWriteLock

some basic questions on how Lucene/search engines work

I'm new to lucene/search engine , and have been struggling with these questions recently. I'd appreciate a lot of you could shed some light on this. let's say I do a query on dog greyhound note that I did not quote them, i.e. this is not a phrase search. what happens under the hood ? which

Re: Re: Re: A likely bug of TermsPosition.nextPosition

I committed another change to 3.x's CheckIndex (to also invoke .nextPosition); can you run that and see if it can detect this? Is there any way I can get this index? One question: how large are your payloads, typically? Does the exception still occur on the index fully rebuilt with 3.1? Mike h

Re: Indexing Non-Textual Data

My question wasn't just about classification. I'm asking, is there a way to classify non-textual data with Lucene? Yes, I know how to Google, and I've read the mailing list logs. All of those results only concern classifying simple text, not arbitrary numeric features. Regards, Chris On Thu, Apr

Hi, I need to run and "AND" query with a twist: give higher ranking for "exact match". So when searching for BIG BEN - Give high rank for the Document "BIG BEN is in London" - Lower rank for "It's a BIG day for my dear friend BEN" Following good advice from this list, I combined 2 separate que

Analyzer which creates terms of one to n words

Is there an analyzer which takes a text and creates search terms based on the following rules: - all single words - "two words in a row" - "three word in a row" - ... - "n words in a row" The reason is the following: I have an index which is now being analyzed using WhitespaceAnalyzer. Besides
