I think the transcribers of the West Yorkshire records have done a fantastic job. There are a lot of errors, but as Nick says we can find our names because we know what we are looking for.
I'm working through mine, and that's all my tree, correcting the names where they are wrong. I can find them, because I had the dates and places from the incredible transcription work done by local FHSs. I've got quite a few who don't show up on a search, but I have found almost all by browsing.
Some of the pages don't have an index at the bottom at present, so they are clearly not going to show up on a search.
Ancestry were reasonably quick in removing "Nomina" as a parish, and replacing it with Huddersfield St Peter. Some of the unindexed pages might be because of that error - maybe they are having to be redone.
