Tags (think category or keyword) can be added to a page to allow it to be found by searching on that tag. When a tag is searched all pages with that tag are listed. To add a tag ,select Insert Tag from the Tool Bar

This will insert this place holder into your page.

{{tag>Insert Tag-Syntax}} 

Now edit it with you desired tag. e.g CAN

{{tag>CAN}} 

or for a two word tag join with an underscore

{{tag>CAN_BUS}} 

or place in quotes

{{tag>"CAN BUS"}} 

for multiple tag words just separate by a space.

{{tag>CAN ADAPTOR SPI MCP2515}} 

The system will add the tag to the Tag Search Index in the background.
