2. Okay – the one issue I can see there, that when I uncheck it resets the settings. That happens because the live loading selector includes the search bar as well, so it resets the search contents to the default.
Please try the following live loading jQuery selector:
#primary .search-result-item>.row>div:last-of-type
3. Make sure you are looking at the correct settings, please check the screenshot. If you remove the options on the Search Sources -> Post type search panel, it will not remove the options.
One more thing, in the ASP meta box on the edit post page, “Additional search tags for this post (space separated)”, the tags are separated by space it should be separated by commas so we can add different terms as keywords.
Thank you for your suggestion, currently it is intentionally made for single keywords. It may change in the future.
