I have managed metadata site columns where I’ve mapped the ows_ crawled property from a library to ‘RefinableString’s in the search schema. The ‘refinable’ box is ticked and I did this a few days ago now. I’m on SharePoint Online so can’t control the search crawls.
These refinable strings can be selected using a search refinement web part and they’re bringing back the relevant values. I just can’t see them to use on the refinement tab on a content search web part. I don't have any other refiners or query terms which would stop results with these properties being returned. Is there something I should check or something that controls their availability on this tab.
