Hey, Kovid, thanks for replying; I'm a huge fan of your work
Anyway, that is exactly what I tried, and it is what worked until a week ago or so. My library was always up to date.
The library now has a very odd behavior. When I add new books to be Full Text Indexed, it gets stuck on a particular number, say 1991 out of 2000.
When I close and reopen the program, that number will have gone up by one, to 1992 out of 2000. However, by using the Full Text Search, I can confirm that the indexing has not worked, as searching for generic terms like "and" or "so" yields no results in that particular book. In theory, I can relaunch the program until it faithfully says "Library fully indexed", but the books in question will have left no trace on the Full Text Search index and will thus not show up in results.
As I said, the other libraries are unaffected until I try to copy the old library over, so I suspect there may be individual books in the library that cause the whole process to go haywire, or that the library is reaching some upper limit [which however seems unlikely, as I have seen users claim to have 10,000+ work libraries fully indexed without problems].
Does this sound like anything that is a known issue?
Best wishes
