Best Bets let you promote selected content when a search query matches a specific phrase. Best Bet content appears at the top of search results because it has a higher boost weight.
Applying Best Bets
Use ISearch or ITypeSearch in EPiServer.Find namespace to apply Best Bets to the search results, as shown in the following example.
var results = client.UnifiedSearchFor("Beethoven").ApplyBestBets().GetResult();
You can apply an overload that accepts a boost index (ApplyBestBets(double? boost)), which affects the influence of a matching Best Bet on the search result score (default is 1000).
var results = client.UnifiedSearchFor("Beethoven").ApplyBestBets(200).GetResult();
