Subject [jira] [Commented] (SOLR-3055) Use NGramPhraseQuery in Solr
Date Sun, 28 Dec 2014 03:56:14 GMT

Tomoko Uchida commented on SOLR-3055:
-------------------------------------

Thank you for your response.

I will add test codes and updated patch to consider other Tokenizers / TokenFilters.

My patch seems to work well for both case, minGramSize == maxGramSize and minGramSize != maxGramSize.
But not optimized for maxGramSize. 
In the case of minGramSize != maxGramSize, using maxGramSize for optimization derives the
best performance improvement. We can examine about that (maybe need another issue.) In practice,
we often set fixed gram size for CJK words as you pointed, so I think it is beneficial even
if it is not optimized for maxGramSize.
