I have a choice field I mapped to a managed property, but it gets no results in search and I'm not sure I picked the right crawled property. In Msft's haphazard approach to this process, there's no clear indicator which crawled property is the correct one. I mapped this to RefinableString08: ows_q_CHCS_Category
And the query which works in other situations, is this:
Where can I find out the differences between ows_q_CHCS_Category, ows_q_CHCM_Category and ows_q_TEXT_Category and which one should be used?
