Hi, > "If you’re changing analyzers, you should rebuild your index using the new analyzer so that all documents are analyzed in the same manner."
It says everything: Take your original data and re-create the index. Indexing is a lossy operation, so you must recreate the index using *all* the original data like it was done the last 2 years. Just use another analyzer.
