Test the difference though. With small docs I experience better speed just re-analyzing...if the docs are big enough TokenSources starts to show an advantage...gotto be pretty big though. Your millage may vary though, so best to check. markharw00d wrote: Anyone care to suggest an approach t

Speeding up highlighting by storing a cached TokenStream

Most of the time the highlighting uses is in getting the next token from the analyzer (tokenStream.next()). I'm wondering how I can access the tokens that are stored in lucene (or store another copy of the TokenStream seperately) and send a pre-tokenized TokenStream to the highlighter so next() is

HTML analyzer

Reloading a searcher

RE: Performance searching over multiple indexes

Using more than one Index will definitely decrease the searching performance. The most Lucene search latency is to load the hits. If there is no hit, the searching takes a short time, dozens milli seconds and it's a const if the document number is less than 1M. search 100 indexes will take 100 time

Performance searching over multiple indexes

There are 2 considerations when caching filter results: 1) What was the criteria used to produce the results? 2) What version of the index were these results taken from? CachingWrapperFilter takes care of 2) by using WeakHashMap keyed on IndexReader. The filter you pass to CachingWrapperFilter m

Re: Lucene Queries Over User-Editable Dynamic Categories of Documents

What do you means by 'Most caches are held in WeakHashMap...' is this caching provided by CachingWrappingFilter or do we have to implement it ourselves? I assume the former. We will share results of our testing as soon as we have any - not sure how generalizable they will be. You have been super

Doron, You definitely added few important (crucial) questions. There are important concerns and I am glad to hear that Lucene community is debating them. I am not an Lucene viscera expert thus I can hardly compare simple search engine from the book with Lucene but it is pity to hear that robust im
