Sandbox now supports 2-way synonyms. 2-way synonyms allow you to define a list of interchangeable search terms. For example, you define a 2-way synonym list with "bread" and "toast". When a user searches for 'bread', the results will include matches for 'toast', and vice versa.

1. Users can define 2-way synonyms in the same tab as 1-way synonyms in Search Engine > Sandbox > Synonyms.

2. Users can duplicate an existing synonym and convert it to either a 1-way to 2-way synonym.

3. Users can also preview 2-way synonyms.
