Working with a customer it seems we've nailed down that searching doesn't return document text results past a certain number of pages of very large archive documents, such as their test with an 18000 page archive document. They could search document text up to a few thousand pages in but then results wouldn't return, even though the Index was regenerated AND the text showed up in the document viewer pane for all pages. Upon splitting up the file into 5000 page chunks the search works fine. This is a workaround but I'm curious if this is a known issue or if a fix might be forthcoming.

LF Server is 10.3.x and there are no other known problems in the system.
