Hmm? I must have missed where it was suggested in this old thread to
enter this "issue" into the bug tracker. At any rate, what I
eventually concluded was that this really isn't an issue, just a
misconception I had about what TXNG3 actually provides as native
indexing support (given the appropriately installed converters).
Assuming the user isn't using Plone or something else that provides a
TXNG hook into the File's data, the user still needs to write the
appropriate adapter to get the indexer to pull the raw data from the
object to then be converted and indexed.
This was a bit of a change from what I was used to with TXNG2 which
does know how to pull the data from File objects. Since I didn't have
enough time to research what was involved in writing an adapter, I
fell back to using TXNG2. It worked well and accomplished what I
