Search Tips
Be concise and specific:
Wrong: I want to learn how to migrate to Trellix Endpoint Security
Right: Trellix Endpoint Security migration
Use quotation marks to find a specific phrase:
“migrate to Trellix Endpoint Security”
Use sets of quotation marks to search for multiple queries:
“endpoint security” “Windows”
Punctuation and special characters are ignored:
Avoid these characters: `, ~, :, @, #, $, %, ^, &, =, +, <, >, (, )
The search engine is not case sensitive:
Endpoint security, endpoint security, and ENDPOINT SECURITY will all yield the same results.
