I was looking up for sentences like #独学而无友. Simplified (#独学而无友) hits CY, GH, whereas traditional (#獨學而無友) hits MOE and HDC. I felt traditional queries tends to hit more results for this kind of queries, but often manually tried simplified queries as well just to see if there's any other results.
Cool! I'll try that!
Updated: With this dictionary groups method, I don't see HDC result. Is this expected?
Updated: Never mind. Disabling the Full text search only option solved the issue, and it's looking good now.
