I currently have an SOSL query
[FIND :finalSearchText IN ALL FIELDS RETURNING FeedItem(Id, Title WHERE Type = 'QuestionPost') LIMIT 10];
This works great for searching the feed item title and body.
What would be preferred is if the query would search for feed items in the title, body and against the topics as well.
Ideally, I would love if the search could return an original post if the replies were returned too.
Does anyone know how to make a query that can search all fields as well as topics?
