'is' & 'is not'

How does 'is' & 'is not' filter work?

'is' filter will pull any given name in the filter.

Example: I want to filter a product title "Airbus Scale model" among hundreds of product titles.

When the filter is applied, the report will show only "Airbus Scale model".

If 'is not' filter is applied, the report will exclude "Airbus Scale model" and show the rest of the product titles.
