Ok I am trying the MemoryIndex, but when compiling I have the
following erro message:
package org.apache.lucene.index.memory does not exist
Is it not included in the lucene .jar?
I currently have the latest lucene binaries.
Moreover:
parse(java.lang.String) in org.apache.lucene.queryParser.QueryParser
cannot be applied to
(java.lang.String,java.lang.String,org.apache.lucene.analysis.Analyzer)
[javac] float score =
index.search(QueryParser.parse("information", "content", analyzer));

Lucene scoring - http://lucene.apache.org/java/docs/scoring.html - uses
pre-computed statistics, location info, and the number of documents in the
index (1 in your case). So some preparation is required before a
(stand-alone) document can be scored against a query.
You could create a single-document in-memory index, with RAMDirectory -
http://lucene.apache.org/java/docs/api/org/apache/lucene/store/RAMDirectory.html
- then you can search and score against that single document index.
Perhaps also MemoryIndex would be useful for you - in Lucene's contrib - I
never used it, but it seems very relevant to your question.
