Synonyms

The synonyms feature allows you to define search terms that should be considered equivalent. For eg: when you define a synonym for sneaker as shoe, searching for sneaker will now return all records with the word shoe in them, in addition to records with the word sneaker.

Typesense supports two types of synonyms:

1. One-way synonyms: Defining the words iphone and android as one-way synonyms of smart phone will cause searches for smart phone to return documents containing iphone or android or both.

2. Multi-way synonyms: Defining the words blazer, coat and jacket as multi-way synonyms will cause searches for any one of those words (eg: coat) to return documents containing at least one of the words in the synonym set (eg: records with blazer or coat or jacket are returned).
