Re: How to search special characters in LUcene

HI Here are the details about my goals. 1. I want to use this lucene for mixed languages. 2. I want to make indexes of the documents which are either english or danish etc. I'm attaching my IndexFiles.java file. When i'm searching i'm giving the index path location as well as doucmets folder.

Re: Why is CustomScoreQuery limited to ValueSourceQuery type?

Steve, I added a patch in https://issues.apache.org/jira/browse/LUCENE-1608, which allows to wrap any query in a value source, and then create a value source query out of it. Let us know how this works for you... Doron On Wed, Apr 22, 2009 at 2:07 AM, Steven Bethard wrote: > On 4/21/2009 10:09 A

Boolean Logic inside a QueryWrapperFilter

Hi Everyone, I have some code that dynamically creates a Boolean query designed to work as a filter. After the query runs I end up with this filter. Filter: QueryWrapperFilter(+(-SourceID:100) +spanNear([ArticleContent:nuclear, ArticleContent:proliferation], 30, false)) My expectation is that

Re: changing term freq in indexing time

The reason I am searching "3 3 2 1" and not "3 2 1" is the reason I asked the question - it is important to include also these frequencies into account when generating these scores. Look at it as if - if a word appears more frequently in a text, is it more important. I managed to make the boosting

Re: changing term freq in indexing time

Hi, I'm no expert on the subject but it seems like you're searching for one term that should be "3 3 2 1" (why do you write "3" two times anyway?). I think you should try a regulalr boolean query where each sub-query is a BoostingTermQuery on one term only. These queries should be used with Occur.M

Re: How to search special characters in LUcene

Are you *also* using the DutchAnalyzer for your *query*? Please show us the index and search code (simplified as much as possible), then we'll be able to provide better suggestions. Also, tell us a bit more about your goals here. Is this an index entirely of Dutch documents? Or is it a mixed-lang

Re: Appropriate analyzer

*If* your terms are simple (that is, not wildcarded), you may get some joy from TermEnum. The idea here would be to find the longest term *already in your index* that satisfies your need and use that to form a simple TermQuery Essentially using TernEnum.skipTo on successively shorter strings u

Thanks Eran, I tried it, adding the classes I copied below and tried to run the following code: [Also I have below a question about the usage of synonyms and BooleanQuery.] DoubleMap wordMap = new DoubleMap(); wordMap.insert("1", 1, 5); // for word "1" we have the world 1, 5 times wordMap.i

RE: Faceting, Sort and DocIDSet

Hi Dave, facets: in you case a solution with one int[IndexReader.maxDoc()] fits. For each document number you can store an integer which represents the facet value. This is what org.apache.solr.request.UnInvertedField will store in your case. (*John* : is there something similar in com.browseeng

SpellChecker locks folder

Hello After I call the SpellChecker.indexDictionary method the directory which contained the lucene index is locked. I cannot rename of delete the folder (windows). In the source of SpellChecker lines 352-353 I see that after the indexing is done the index is reopened: searcher.close(); sea
