> The only thing that is suspicious to me is the > EnglishPorter. Yes you are right. "ion" part of the term was deleted by it. You can verify this using /admin/analysis.jsp page. It will tell you which TokenFilterFactory removes it. > I've deleted from the configuration but nothing changes. Should > I reindex the collection to see the changes? Yes re-index is necessary. > Should I delete also from the index section? You should remove English porter from both query and index analyzer. > What I will loose deleting English porter? You will lose stemming functionality. But since you have spanish, portuguese and english documents using English porter for all the documents is not meaningful.
