In Amazon, a General Search will show all results. An Advanced Search utilizes operators in the search bar to filter the search results.
Use Advanced Search in Amazon and place a "-" in front of the word you want to exclude. This should exclude the words you want to exclude from an Amazon search. That is for Advanced Search by just using search terms. It is like the following. The example is below as to what I mean.

Example:
cats -dogs

The word, dogs, should be excluded. Please note, this is for the current year, 2023. Over time, the operators may change. As changes are made to Amazon, things may change. For the 'not' operator, that is possible.

 

That syntax ceased working some time ago, unless you are referring to a special ‘Advanced Search’ link. If so, I find no indicator that that is even a thing, but would love to know if there is such an animal. Ebay has one.

Searching Help for Advanced Search only produced info on the filtering options to the left of each results page.
