Use Query enhancement to help users find relevant results

You may want to help users find the information they are looking for, even if the words they use in their query aren't exactly the words used in your content. By setting up Query enhancement (synonyms), you can expand your users' queries with variations of a search term. 

For example, you can define "assassin" as a synonym for "ninja." When a user searches for "ninja" with your search engine, they will also receive results for "assassin." 

Programmable Search Engine supports a maximum of 2000 synonyms per search engine.
