Hi all,
Now search results of "commodity" changes:
* Commodities <http://en.wikipedia.org/wiki/Commodities>
Relevance: 100.0% - -
* Commodity <http://en.wikipedia.org/wiki/Commodity>
Relevance: 95.4% - -
* Commodate <http://en.wikipedia.org/wiki/Commodate>
Relevance: 94.7% - -
* Commode <http://en.wikipedia.org/wiki/Commode>
Relevance: 94.6% - -
I suggest that you may want to index "Title" with StandardAnalyzer and
"Content" with SnowballAnalyzer,
since the title field of Wikipedia is almost all named entities that
should not be modified at all.
IMHO, to have a mixture of original words and stemmed forms is a good
heuristic rule though,
but it is only suitable for content field.
Sincerely,
