Yeah I decided to beef up the filtering system because the search parsing is very limited and will match the entire search term in all supported search fields, so even implementing a search feature for custom columns (which won't happen because it would be a performance nightmare and require me to rewrite the search part from scratch) would not have helped much. But adding this was relatively painless, even though it requires some gymnastics to get all the data needed for this to work in a query without offloading too much work on the user. Using your own product is a great motivator for these kinds of things
