Location of code which determines a Hit for PhraseQuery

Hi, I am trying to work through the Hit collection process for a PhraseQuery (using an exact phrase). For an example search, say I'm looking for: "lucene action" (quotes indicating exact phrase) in a one doc, one field index consisting of: wow, lucene rocks, lucene action items are cool, v

Re: lia demos without ant

Hi Gasi, Please see page xxxii in LIA, section Author Online, and use that for LIA questions, so we don't bother others with LIA-specific stuff. However, your problem doesn't have to do so much with LIA, either. It's a basic Java question, and it looks like the part that you have been misunderst

lia demos without ant

Hallo, IBecause of less or better say no experience in Ant I try to run some demo applications out of the LuceneInAction Examples folder. For example I wanted to test AnalyzerDemo.java. I set the -classpath c:/LuceneInAction/lia/analysis because there is AnalyzerDemo.java on my system. I tried

MultiSearcher "refresh" when underlying searchers need to be recreated?

Hi I have a general question about the cost of creating MultiSearchers. Suppose you have created a MultiSearcher using a large number of IndexSearchers, let's exaggerate to highlight the issue and assume we put an array of 100 IndexSearchers over large indexes in the MultiSearcher constructor.

Re: Updating the index and searching

The best advice I can give on this topic is don't open a new IndexReader for every search. There is a lot of caching that goes on under the covers (particularly when you sort by things other then SCORE) which is completely wasted if you open a new IndexReader everytime. If you use Filters, then

Re: limit lucene result

The Hits object retrieves the documents lazily, so just ask it for the first 100. -Yonik On 9/7/05, haipeng du <[EMAIL PROTECTED]> wrote: > > The reason that I want to limit returned result is that I do not want > to get out of memory problem. I index lucene with 3 million documents. > Sometime

limit lucene result

The reason that I want to limit returned result is that I do not want to get out of memory problem. I index lucene with 3 million documents. Sometimes, searching will return millions of fields back to me. I just want to get the first 100, for example , to show them to user. Even, I use search(query

Re: limit return results

You normally just can't break out of the HitCollector and get meaningful results. The problem is that you get unordered (or rather index order) results from a HitCollector, not ordered by score or any sort. To get the highest 100 docs by score, you normally need to see *all* the hits. On 9/6/05

Updating the index and searching

Hello, I have an index into which documents get added and updated (by deleting and adding). When I run queries on the index these have to take into account all changes on the index so I open a new IndexReader. What I am finding is that when the index is large the opening of the index takes a c
