We have a SharePoint online team site with a custom list having few items. This list has a single selection lookup column with name "IssueType". I want to use this field as a refiner in my search for items on this list. There is an index on IssueType column and search is enabled on list. I reindexed the list few times yesterday (> 24 hours ago). Still the crawled property for this IssueType column is not coming up in the search schema. However, for another lookup column crawled property is coming up.
Please let me know how can I fix this issue and troubleshoot missing crawled properties. Also, do refiners work for multi-lookup columns?
