After some research on Anaylzers and mappings it appears that you cannot change a mapping after it has been indexed.
Unfortunately I'm using the JDBC river 1.5.2 and it is mapping Email addresses as strings.
Since it is already indexed as an Analyzed string I cannot find email addresses properly.
It doesn't appear that I can reindex so any Ideas on what I can do? Can i modify the river to let it know not to pick an analyzer? Lots of data to be reindexed and every one thinks the Search sucks because it can't find a simple email address.
