Aha! Brilliant! Thank you. That is much better. A game changer!
The next issue is that I am having trouble searching for strings with one letter words. eg. Vitamin A. I have set primary keyword logic to AND with exact matches, and min word length to 1, but a product with “Vitamin A” in the title, content and category is subordinate to other products that don’t have it in the title or category, and lots of other categories are returned above it.
Another niggle is that products with none of the restrictions checked (eg books) are still returned. Is it possible to stop that?
Thank you.
