Full-Text Index Searches On A Read-Only Replica

You learn something new every day.

Client wanted to offset the Full-Text Index searches onto the Read-Only Replica of an Always-On Cluster.

Wasn’t too sure exactly how to go about it, but did some research and came across the below MSDN article which mentioned the exact thing I was after:

“full-text indexes are synchronized with the secondary databases”

So all I need to do is install the Full-Text Search feature on the Read-Only replica and Full-Text Searches will be conducted on the Read-Only replica with no further configuration needed.
