This is based on the below blog post which stated the following. "Can I use Search, the built-in search function in Episerver CMS, instead of Find?Viktor: I wouldn't recommend it. A key value of the DXC Service is its automatic-scalability. Search is file-based, and gets corrupted when the DXC Service scales and the index ...

Description The article describes the issue when trying to add sorting of non-BoostMatching results with BoostMatching filtered results. The issue is that when adding sort to the results it will be ordered in that sort order only. The "score"-mechanism will be replaced, which makes BoostMatching useless. This is by design. For more information on Boosting with filters please see here. Resolution It is possible to first order by some property and then by score. This would ensur...
