Hi Ivan, No, we do not use StandardAnalyser or StandardTokenizer. Most data is processed by fTextTokenStream = result = new org.apache.lucene.analysis.WhitespaceTokenizer(reader); result = new ISOLatin2AccentFilter(result); // ISOLatin1AccentFilter modified that ö -> oe result = new org.apache.lucene.analysis.LowerCaseFilter(result); result = new org.apache.lucene.analysis.NGramStemFilter(result,2); //just a bigram tokenizer
We use our own queryparser. The bigramms are searched with a tolerant phrase query, scoring in a doc the greatest bigramms clusters covering the phrase token.

If you use StandardAnalyzer (that uses StandardTokenizer) may be the reason is in it. You can see the pre last report in the thread "Indexing Speed: 2.3 vs 2.2 (real world numbers)". According to the reporter Jake Mannix this is because now StandardTokenizer uses StandardTokenizerImpl that now is generated by JFlex instead of JavaCC. I am asking because I noticed a great speedup in adding documents to index in our system. We have time control on this in the debug mode. NOW THEY ARE ADDED 5 TIMES FASTER!!! But in the same time the total process of indexing in our case has improvement of about 8%. As our system is very big and complex I am wondering if really the whole process of indexing is reduces so remarkably and our system causes this slowdown or may be Lucene does some optimizations on the index, merges or something else and this is the reason the total process of indexing to be not so reasonably faster.
