Hi,

It sounds very strange to me - as long as your metafield has required attributes (Searchable/Include in default search) it should be shown in the result. Do you have the full stacktrace?

/Q

Here is the trace - the Query to find is quite large.

Note, this is all generated by Commerce's Promotion page using the Find Catalog Entries search dialog.  There has been no setup to choose specific meta fields.

I have no clues what is wrong - but we are releasing FindSearchProvider 8.13.1 today. Would you mind to give it a try?

If it still does not work - contact our developer support service for further assistance.

/Q

Did you find a solution to this? I'm encountering a very similar solution since I updated EPiServer.Find to version 12.
