Search stops working

[Smith-Corona]

hi,

Lately I've found from time to time that Search just stops working. No matter what I put into the search box, nothing comes up. I'm putting in search terms I know are present, I'm making sure I'm using Simple search, I press Reset - still nothing comes up when I press Search.

The only way to make it work is to close the database and re-open. Then the self-same search works.

Has anyone else encountered this?
