I have created a site column called "mySiteCol1" and performed search such that this column must be populated in the Refiners tab on Search Results Web Part and I can filter the search results.But the column itself is not populated in this tab. What may be the issue that, this site column is not populated? I have already performed full crawl,checked the checkbox for Refineable and sortable and generated managed properties. Any extra configuration do I need to add in the search schema or search results web part.
In order for properties to show up in the Refiners you'll have to make sure that the Managed Property has at least
Queriable checked and
Refineable set to Yes - active.
Also make sure to update the Refiner webpart on the search page to include this Managed Property.
Do you check Searchable for managed property?
Is your managed property mapped to crawled property of mySiteCol1?
Are search results you get related to the value of the managed property? Refiner value only is shown up when having relation with search results.
