@standoutpk I didn’t end up using the plugin that particular time as I just used a custom function in functions.php rather than installing the plugin for my project. Its a good plugin but unless I was going to use the settings then a function was sufficient for me.
I didn’t have to do anything to make it work – simply installing the plugin was sufficient it worked straight away. Check the plugin settings I can’t recall if its enabled by default to search those fields.
what did you mean by having checked the postmeta?
Here I meant that I was able to confirm that the search was indeed including the ACF fields in the search as my tests were based on specific search terms I added and I checked/compared the postmeta to confirm the accuracy of the results.
