Does uppercase matter in html|contains.

[xVoid879]

I was making a phishing kit detector and one of the three detectors was

exampleText:
  html|contains:
    - "example"
    - "Example"
    - "ExAmPlE"

Now, lets say I only put example there,

exampleText:
  html|contains:
    - "example"

Would it still detect sites with the words Example or exAmPle, one of them, or none?
Thanks for any help!
