eugenepi on "[Plugin: BuddyPress Global Search] why should i do to hide search results for certain keywords"

Hello, thanks for making this plugin, I'm using it very well.
Is there any way to hide search results for certain keywords?
For example, when the search term is 'hello', How could I hide all the results containing that word?

thanks in advance!
