Merging 2 indexes

Hey all I have 2 indexes. Both have an ID field and one or more String fields... I want to merge these indexes by merging the documents on each index that match their IDs. For exmaple: Index 1: Doc1: id: 1234 (*) text:bla bla text:abcd Index2: DocA: id:1234 (*) text:xyz (*) ID's match So I

Can you tell us a bit more about what you custom query does? Perhaps you can build the candidate filter and reuse it over and over again? karl 30 aug 2008 kl. 03.34 skrev Matt Ronge: Hi all, I am working on implementing a new Query, Weight and Scorer that is expensive to run. I'd

Re: MoreLikeThis return no results

MoreLikeThis needs to find the terms in your doc. It tries to do this by using TermFreqVectors which are stored in the index if you choose to add them at index-time. If you haven't done this then it will fall back to reanalysing the content of the document usings an analyser (despite what the

Beginner: Specific indexing

Hi guys, Fairly new to Lucene, and just finished reading Lucene in Action. My problem is the following I need to index the documents that only contains the following pattern(s) in a mass of documents: tag #1 #2 tag is a fixed list of words #x are small numbers 100 My idea is to simply build a

Re: Trouble Boosting BooleanQuery's with Multiple Clauses

: When I create a TermQuery, add it as a SHOULD clause to a BooleanQuery, and : boost that BooleanQuery, the boost shows up when I run : IndexSearcher.explain(). However, when I add a second TermQuery as a SHOULD : clause to that same BooleanQuery, and still boost the BooleanQuery, the : boost is
