How does contain & doesn’t contain filter work?

The contain filter is used when you have any specific word contained in a phrase

Example: I want to filter the products which contain apple.

Now the store contains many products like Sony headphones, Bose headphones, Sony Tv, apple charger, apple iPhone 5, apple iPhone 6, apple iPhone 7, apple Mac computer, apple headphones, apple mouse, SanDisk music player, SanDisk Pen drive, Seagate Hard disk, HP laptop etc

When the contain filter for the product apple is applied the report will pull only the apple products since all the product have the name apple in common i.e., apple iPhone 5, apple iPhone 6, apple iPhone 7, apple Mac computer, apple headphones, apple mouse

Similarly, When the doesn’t contain filter for the product apple is applied the report will pull only the Non-apple products i.e. Sony headphones, Bose Headphones, Sony TV, SanDisk music player, SanDisk Pen drive, Seagate Hard disk, HP laptop.
