It seems very odd to me that the original value would show up twice with the preserveOriginal parameter set, but I am seeing the same behavior on 4.7 and 5.3. Because both copies are at the same position, this will not affect search, but will slightly affect relevance if you are not specifying a sort parameter. Everything else about the analysis looks correct to me, and the positions you see are needed for a phrase query to work correctly. I have seen working configurations where preserveOriginal is set on the index analysis but NOT set on query analysis. This is how my own schema is configured. One of the reasons for this configuration is to reduce the number of terms in the query so it is faster than it would be if preserveOriginal were present and generated additional terms. The preserveOriginal on the index side ensures a match whether mixed case is used or not. Thanks, Shawn
