Failed to create text index reader for .frq file

Hi, I am facing a error while processing a set of data.. the description says "Failed to create text index reader for .../.../_166.frq (The System cannot find the specified path). I have never seen this error in the past neither have I seen this file in the index folder ever. Does lucene take ca

Lucene index update

I've written a blog regarding a work around for updating index in Lucene using parallel reader. It's explained with results and pictures. It would be great if you have a look at it. The link: http://the10minutes.blogspot.com/2010/10/lucene-index-update.html

using ParallelReader to update a document

I am trying to find a work around for updating fields and in turn the documents in the original index. I am using parallel reader and providing it two index, the second index being the first to be seen by parallel reader. The second index has same number of documents as first index[in this case,

Parse multiple fields using Queryparser

I have many fields in my document and want to parse my query including each of them QueryParser parser = new QueryParser(Version.LUCENE_29, "Field2",new StandardAnalyzer(Version.LUCENE_29)); Should I create multiple parsers in this case or is there any other way round?

Update lucene index

Hi Group, I understand that the process of updating a document in lucene index is to delete the document and add it again. But I do not want to delete the document. I was thinking of a approach where I can create a new index with only the fields I want to update. And then may be I can some how me
