Yet another NFS Question...

Hi everyone, There has been a lot of discussion regarding Lucene+NFS pitfalls. I'm not sure how to proceed with a more distributed operation. I'm trying to take the indexing load off of our search server. I can do this either by building a new server which hosts the Indexer and the Index, or a se

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

bably unrealistic. The stuff you want to achieve normally works by either placing objects into the HTTP session (user-bound) or attaching them to your application context (application-bound). Regards, Mindaugas On Tue, Apr 21, 2009 at 5:01 PM, David Seltzer wrote: > Hi All, > > Sorry fo

Servlets Sharing Resources

Hi All, Sorry for the slightly off-topic question, but I've just run into a gap in my understanding of Servlet programming. The question: Is it possible for two servlets to share access to an instance of IndexSearcher or an IndexReader? I'm thinking about setting up a Search servlet to provide XM

ent/how many in average? INDEXORDER means document number. MultiSearcher works also fine: If you have one index for each year and for each of this indices the indexorder in order of date, also the MultiSearcher will have correct INDEXORDER: Take a look to the variable "int[] starts" in Mult

Faceting, Sort and DocIDSet

itCollector and sort by a field? 2) Is using BitSets the wrong way to quickly generate facet counts? I've read about DocIDSets, but I'm not sure how to use them in the same way. (I'm basing my faceting technique on Sujit Pal's article http://sujitpal.blogspot.com/2007/04/lucene-

have to mark the field as Field.Store.YES in order to see that field when you retrieve the doc at search time. You'll then be able to retrieve the string value. Mike On Thu, Apr 2, 2009 at 10:45 AM, David Seltzer wrote: > Hi All, > I have a document with a field called "Text

Retrieving TokenStream from Tokenized Non-Stored Field

Hi All, I have a document with a field called "TextTranscript". Its created using the following command: myDoc.add(new Field("TextTranscript", sTranscriptBody, Field.Store.NO, Field.Index.TOKENIZED)); I'm then trying to retrieve the TokenStream by pulling the field. Field fTextTranscript = lucDo

Using SpanNearQuery.getSpans() in a Search Result

Hi all, I'm trying to figure out how to use SpanNearQuery.getSpans(IndexReader) when working with a result set from a query. Maybe I have a fundamental misunderstanding of what an IndexReader is - I'm under the impression that it's a mechanism for sequentially accessing the documents in an

Sort Performance Question

Hi All, I have a sort performance question: I have a fairly large index consisting of chunks of full-text transcriptions of television, radio and other media, and I'm trying to make it searchable and sortable by date. The search front-end uses a parallelmultisearcher to search up to three
