Contributing

Goodmorning, I'm Danilo Cicognani from Italy. I would like to contribute to the develop of Lucene for the company I'm working that is "Tinfo Srl". For the first step we would like to make an analyser for the italian language (which is not present in the sandbox). This is the first step to start usi

IndexReader.getVersion()

Hello, Am I missing an obvious way to return version of already opened index? Static method IndexReader.getCurrentVersion() uses SegmentInfos to read version number from "segments" files. This returns current version of index in Directory but I need a reliable way to obtain version of IndexReader

Re: Contributing

Danilo, Welcome! We'd love to have your Italian analyzer as part of the contrib/ analyzers codebase. The easiest way to get your contribution accepted is to follow these steps: * Be sure to use the Apache Software License 2.0 * Fit your code into the structure in Lucene's Subversio

Hi Danilo, You may want to look at the ItalianStemmer and SnowballAnalyzer, as they may already do what you need for your company: http://www.lucenebook.com/search?query=italian+analyzer http://svn.apache.org/viewcvs.cgi/lucene/java/trunk/contrib/snowball/src/java/net/sf/snowball/ext/ ciao, <--

Re: DO NOT REPLY [Bug 34995] - Contribution: LuceneIndexAccessor

What I described is really nothing more than a few methods like this: public void index(Indexable data) throws IOException { synchronized(_directory) { IndexWriter writer = getFSWriter(); try { Document doc = creat

Which scorer to use for disjunctions?

Dear readers, At the moment it's not clear to me which code is best for scoring disjunctions: There is a specialised priority queue for DisjunctionScorer: http://issues.apache.org/bugzilla/show_bug.cgi?id=34193 This also contains: - a btree implementation of BooleanScorer by Karl Wright that is

RE: major searching performance improvement

I will look at separating it out. I wanted to get initial feedback before moving on. 1. I agree that the initialValue() is the way to go. I'll make the changes. 2. I agree that creating NioFSDirectory rather than modifying FSDirectory. I originally felt the memory mapped files would be the fastes

RE: major searching performance improvement

It is my understanding of memory mapped files is that the file is assigned an address range in the virtual address space, and using the MMU/paging facilities the file is mapped into that range. Java cannot work with memory pointers directly, so there is at minimum some JNI calls that are made when
