Can you use the search feature on this site to search for free fonts that can be used for Commercial Use only ???

In the search form, next to the submit button, click on "more options".
Then check the following boxes : "Puclic Domain / GPL / OFL" and "100% Free"

Thank you Damz. Another question. Is Public Domain / GPL / OFL the same as giving the user rights to use the font as commercial use?

a bit of reading for you

Where is the search bro?

Sorry, it's not a "search form"
on each theme of the website, there's the preview form. The "more options" link is next to it.
