Re: FieldCacheImpl mistake?

Thinking about this a little more: my short term advice to you would be to use FieldCache.getCustom with your own SortComparator that just returns the Float/Int value parsed fro mthe string ... the Comparable[] should default to "null" for any doc that doesn't have a value for the field, so you'll

Mark: Thanks, that reassures me that I'm not hallucinating. If it gets on my priority list I can certainly share the code, since I stole it in the first place . I have a semi-solution for now that gets me out from under the immediate problem, but it really wants a more robust solution than the on

Re: Multiword Highlighting

Good catch Erick! I'll have to tackle this as well. Mark H is the originator of that code so maybe he will chime in, but what I am think is this: In the getSpansFromBooleanquery, keep track of which clauses are required. Then based on if any Spans are actually returned from getSpansFromTerm f

Re: NO_NORMS and TOKENIZED?

I originally added it without an Index param at all. I can't say I'm a fan of the way Field currently does things, and I didn't want everyone to pay the price for yet more options. Look at the code for the Field constructor: public Field(String name, String value, Store store, Index index, Term

Lucene index in memory

Hi all, I want to understand how lucene searches its index -- does it load the whole index into memory at once? Is there any way to make sure that it does so. I want to optimize maximally on the search time required by lucene on over ~7M short documents. The queries that I deal are 6 to 7 tokens

I hope you're all following this old thread, because I've just run into something I don't quite know what to do about with the SpansExtractor code that I shamelessly stole. Let's say my text is "a b c d e f g h" and my query is "a AND z". The implementation I stole for SpansExtractor (mentioned s
