In the trunk, see contrib/spatial. I believe it is all committed and being worked on by interested contributors: http://svn.apache.org/repos/asf/lucene/java/trunk/contrib/spatial/ -Grant On Mar 18, 2009, at 12:05 PM, Jamie Johnson wrote: I am working on a project that is already using Lucene

I am working on a project that is already using Lucene (through Hibernate Search) to perform full text queries and have since come across several sites with information about LocalLucene/Lucene Spatial. I was wondering if there was a timeline for having this work implemented that anyone was aware

Depending on your corpus, a semantic vector enabled search engine definitely is more semantic than one without. The general approach I have with these is: - get a query - expand each terms of the query with the fuzzification of semantic- vectors (e.g. if requested for termA, add termB and ter

hi Paul, I am new to this field of search engine. My aim is to develop a semantic search engine. Initially I was trying to develop that by using LSI. But since it is patented that is why there are no many implementation attempts. I want to ask is it possible to create a search engine using lucene

Nitin, LSI is patented so it's not been a flurry of implementation attempts. However, SemanticVectors is a library that does similar approaches to LSA/LSI for indexing and is based on Lucene's term-vectors. paul Le 18-mars-09 à 07:09, nitin gopi a écrit : hi all , has any body tried to us
