Is there a way in DNN 6.0 to automatically reindex the search results. Because unless we click on host->Search Admin->Reindex Content some of the recently uploaded content would not appear in search results until the content is manually reindexed. I wish to know if there is a way to automate this process so that it'll happen on a daily basis. Thanks in advance.
The "search engine schedule" should handle this for you. It's possible that the schedule is disabled or needs to be run more frequently, check under Host > schedule.
