Hi,
It highly depends on how the search is configured. Unfortunately I can’t see the configuration from the front-end only, but the most likely reasons are an incorrectly set keyword logic, an possibly partial/fuzzy matches within other fields.
I suggest trying the following:
– Using a primary/secondary keyword logic for whole and fuzzy matches like so: https://i.imgur.com/kd40s6B.png
– Also using the index table engine – this will make whole keyword matches much more accurate
