indexing excel file

Hi, i want to index an excel file with nutch and i have the following error: http://dev.torrez.us/public/2006/pundit/java/src/plugin/parse-msexcel/sample/test.xls: failed(2,0): Can't be handled as Microsoft document. java.lang.ArrayIndexOutOfBoundsException: No cell at position col1, row 0. I

Is storing 20 fields in a lucene document desirable?

Our document contains a total of 23 fields in one document and we STORE all of them in lucene index. We have recently had some performance issues and our analysis has shown the bottleneck to be lucene search and retrieval. We have been thinking about reducing the number of fields per document

Re: Scoring for all the documents in the index relative to a query

You can also rely on that by default documents are collected in-docid-order. You can therefore use your own hit collector that when collecting doc with id n2, assuming the previous doc collected had id n1, would (know to) assign score 0 to all docs with: n1 id n2. In other words, you can know

Custom query parser

Hi, I am willing to have a query parser which is fault tolerant. I have search over the archive, and I have found this : http://www.nabble.com/Error-tolerant-query-parsing-tf108987.html#a300382 I also want my parser to have very simple feature : phrase search and field search. So I need to

Re: Is storing 20 fields in a lucene document desirable?

How are you doing your search? When you say lucene is the bottleneck, that encompasses a lot. You really need to pinpoint things a bit more 1 are you iterating over the hits object for many docs? This is bad. 2 are you using a HitCollector and reading the doc each time you get to the collect

MoreLikeThis and setBoost

I've been stepping through the contrib MoreLikeThis class and was wondering if people can give opinions on why you would or would not use setBoost(true) for the MoreLikeThis object. It seems a bit odd (at least to me) to boost the good terms in the query (based on the term's score), since

Re: Scoring for all the documents in the index relative to a query

: Well, the javadocs as patched at LUCENE-584 try to change all : the cases of zero scoring to 'non matching'. I'm very out of the loop on LUCENE-584, but i think supporting scores = 0 is an important use case that shouldn't go away ... it makes CustomScoringQueries a lot morepowerful, and

Re: indexing excel file

There is absolutely no reason to send seperate, identical, emails to solr-user, nutch-user, and java-user ... particularly when it's clear from past emails you knew your question was specific to nutch since you'd already asked it on nutch-user 4 days earlier...
