Sure!
I am very sorry for no response, it almost never happens with me. Unfortunately I was only able to respond to some minor issue tickets as there was a family medical emergency, I will be back on friday though. I should have let you know, sorry about that.
I am not sure about the custom fields, if they don’t pop-up in the custom fields search list, then there is a chance that they are not wordpress custom fields, but data that might be stored in a different table or something similar to that. Often times the field names are just very hard to find, but sometimes they are indeed stored outside the metadata table. Generally that is not searchable by any plugin, as the data has to be accessible through code fields. If that is the case, then the only chance is to fetch them through an API to the index, however that needs some investigation, which I can’t do at the moment. In case you are aware of a programmatical API for the plugin, please let me know where I can find it and I will look into it as soon as I get back to the office.
The URL issue is much simpler in my opinion. The search requests all URLs to post types through wordpress to always get the correct link. Sometimes some plugins however doesn’t hook into that filter and a generic URL is returned – or there is a different reason in relation to that one. URL redirect is a very acceptable solution. If they have an API, then this can be also resolved via a small custom code snippet to fetch the correct URLs.
I will get back to you on friday if that is okay, if not then I will initiate a refund, whichever fits you better. Just let me know.
