Thanks Reth for your response. When validator is changed to validate, both at query time and index time, then should not validator*/validator return the same results at-least?
E.g. 5 documents contains validator. At index time validator got changed to validate. Now when validator* is searched it will also change to validate and should match all 5 documents. In this case I am not sure how the wildcard internally is handled meaning what the query will transform to. Please help me understand the internals of wildcard with stemming or point me to some documents as I could not find any details on it.
