Re: Highlighter doesn't highlight wildcard queries after updating to 2.9.1/3.0.0

OK, to answer my own question: I found from the following issue that if I do a query.rewrite(), highlighter doesn't work. https://issues.apache.org/jira/browse/LUCENE-1425 I did rewrite() in order to find all matched terms for example in a prefix query, but as this doesn't work anymore like Lucen

Re: Highlight the whole sentence instead of the partial matching terms

Just figured out, missed "lucene-memory-2.4.1.jar" external jar inclusion. With that jar included, "\"Giving and\"~11" only got "Giving" & "and" highlighted but not the whole sentence, any ideas? Thanks, 2010/1/11 Li Leon > *Hi all,* > ** > *I wanted to use to following code to highlight the w

Re: Highlighter doesn't highlight wildcard queries after updating to 2.9.1/3.0.0

The problem comes from this method: org.apache.lucene.search.highlight.WeightedSpanTermExtractor.extract(Query, Map) The query passed to this method is of type org.apache.lucene.search.ConstantScoreQuery, but it matches non of 'instanceof' checkings in this method, so no WeightedSpanTerm is extra

Re: a complete solution for building a website search with lucene

You should really look at Nutch. from the website http://lucene.apache.org/nutch: Nutch is open source web-search software. It builds on Lucene Java, adding web-specifics, such as a crawler, a link-graph database, parsers for HTML and other document formats, etc. so

Hi, Have you implemented such web search in your web application development?  As detailed as possible. example: 1) index: ? 2) search: Lucene Please do advise. Thanks. --- On Sat, 9/1/10, Simon Willnauer wrote: From: Simon Willnauer Subject: Re: a complete solution for building a websit

Re: Is there a way to limit the size of an index?

I'm storing and reading the documents using Compass, not Lucene directly. I didn't touch those parameters, so I guess the default values are being used (I do see cfs files in the index). How the ramBufferSizeMB parameter affect the files size? What value should I use in order to have 6MB files?

Re: Is there a way to limit the size of an index?

What did you set your IndexWriter ramBufferSizeMB to? That controls how large the initial segments are. Are you using compound file format? (that's the default). Mike On Sun, Jan 10, 2010 at 7:03 AM, Dvora wrote: > > Oh, as an excercise I tried to create 6MB files. Using the rule mentioned >

Re: Is there a way to limit the size of an index?

Oh, as an excercise I tried to create 6MB files. Using the rule mentioned before, I set the maxMergeMB to 0.6 (and then 0.62, 06.64... 1.8) and used the default mergeFactor - I thought that should do for 6MB files... Michael McCandless-2 wrote: > > What settings did you use (mergeFactor, maxMe

Re: Is there a way to limit the size of an index?

What settings did you use (mergeFactor, maxMergeMB)? "nothing in the middle" is normal. Segments sizes are often rather quantized, for a newly created index. Ie a bunch of segs will be 1 MB, a bunch ~8, a bunch ~64 (assuming the IW flushes at ~ 1MB and mergeFactor is 8). Mike On Sat, Jan 9, 20
