My admin search function stopped working

[cFrizzell]

When I log in to my Zen Cart admin and go to Categories / Products and try to use the search field to find a particular product the function returns nothing, no message, nothing, just like the product doesn't exist. This feature used to work fine up until I used Inventory Source to upload more products to my web site. Do you have any idea what has happened? Nobody seems to want to help me with this problem. Can you suggest something?

If you look via phpMyAdmin at your database, do all of your Products in the table:
products

have correct values in the fields:
master_categories_id
products_price_sorter

specifically the Product that you were searching for?
