Disabling Search Suggestions
When someone is searching on your site, they may misspell a word. The search results page will then display a suggestion "Did you mean:" phrase. It can be good for misspellings, but it can also bring up unnecessary suggestions as you can see in the example below. It is possible to turn this feature off if you find it is not helpful to shoppers.
1. Go to Store Setup › Store Settings, then click the Display tab.
2. Uncheck the Enable Search Suggest? setting, then Save your changes.
