Synonyms are automatically stemmed using a minimal English algorithm. There is no need to create singular and plural versions of synonyms.
For example, a synonym that expands
tablet will also expand
You can enter multiple values into the expansion of a 1-way synonym, or into the 2-way synonym. Multiple synonyms can be entered using the following formatting.
Values are separated by commas
aaa, bbb, ccc
Any value that includes double-quotes or commas must be enclosed in double-quotes
aaa, "1,000", ccc
If double-quotes are used to enclose a value, then a double-quote appearing inside a value must be escaped by preceding it with another double-quote
aaa,bbb,"world's ""best"" product","""products"""
would be the format for the values:
world's "best" product, and
Overuse of synonyms will slow down your search. There is a limit of a 100 synonyms per entry. This limit includes the triggering terms for a 1-way synonym. When you add more than 4 two-way synonyms, you will incur slower queries. Each additional synonym slows down your performance. The correct way to address underlying data gaps is to tag your products at record level, as this will leverage the search engine’s performance capabilities via indexing.
