I found this unique setting and thought - awesome. We just built a brand new server and migrated 100 domains over this weekend. Propogated this to every user. My problem is that everytime I go in to the User Defaults it resets this back to "Generic Indexer" rather than "English" that I set it to. This means all new users will get the generic indexer.

Now comes the question of what does this do? Is it truly designed for english as users complain they can't find things like "bill", "deposit", etc. in email body/subjects. They show us this is there and when they search no results are found. How can we get it so results are found? We have reindexed the users still with no success.
