Hi,
Thank you for the details, it helped a lot!
The main issue was, that you had the exact matching enabled – in which case the search phrase entered must match “as-is” at least partially to either of the selected fields.
When exact matching is disabled, then the word order will not matter. I went ahead and did that for you, I swtiched to the “and” keyword logic as well. The index table was also disabled, so I enabled it for much more relevant matches.
Currently I don’t see any exam titled “ABRSM Jazz Piano Grade 3 2023” or having these keywords (or parts of them) in the title, so these keywords will very likely yield no results.
If you want to have a bit more broad results as well, you can enable the secondary logic, so that if there are no matches, the plugin will try to suggest matches to either of the keywords. Usually using the “or with exact matches” is a good starting point.
