I tried searching for "Item Name" and a string,

The SQL query tried to use "stock_id" LIKE '%%', which is:

a) a NOOP, IMHO
b) invalid, because stock_id is INTEGER and LIKE requires character strings,
c) I did not selected "Stock ID" as property to search for,
d) I miss the search string I entered

I also miss the properties I've created, in order to search through them.
