Running into an issue with refinement panel search results. We have added a choice column and added data to the document metadata, set up the metadata mapping property for the column and added it to the refinement panel as normal. I then did several full crawls after which the refinement category and results show up. The documents also show up in search results as would be expected. Now when clicking on the refinement for the document, almost all of the documents dissappear from the results. The only ones left are a few that seem to be showing the search refinement in the document text only, not in the title, etc.
I have done the refinements in the past on SP2010, but not for a few years. Any thoughts about what could be wrong?
