Best Bets can be used to promote certain content when search query matches specific phrase. Content included in the Best Bet will appear on top of the search results, as those hits will have a higher boosting applied to them.
Applying Best Bets
In order to apply Bets Bets to the search results ApplyBestBets extension method should be used for ISearch or ITypeSearch in EPiServer.Find namespace:
var results = client.UnifiedSearchFor("Beethoven").ApplyBestBets().GetResult();
There is an overload that accepts boost index ApplyBestBets(double? boost). This boost index affects how much influence a matching Bets Bet will have on the search results score. By default boost index is 1000.
var results = client.UnifiedSearchFor("Beethoven").ApplyBestBets(200).GetResult();
