Thank you! Yes, I reindex. I store the file timestamp along with the contents, so it's not quite as involved as it could seem but startup does take a bit. And, I don't have a good way of discovering deleted files at the moment. Not a big deal as it is, but something I will look into.
And yes, query suggestions are exactly what I mean. Thank you for informing me, I guess I will have to look into how I can make it myself :-)
