Search & Discovery - Synonyms, size search results

[Deanosaurus]

Hello, 

Looking for some help.  How do you add synonym to display in search results example:

1000mm to display as 1000 or 1000 display as 1000mm.

For example in my store i can search 1000 door will return 0 results, if I search for 1000mm door, it will return the products.
