The event and player searches in play.fiba3x3.com are both tag-based.
Start by writing something to the search bar such as "Finla" and
- you'll see different suggestions below in the suggestion bar such as "search event by organiser","search events by country","search events near city"
- move your mouse and click your selection and the search tag moves up to the search bar
- repeat to get more tags or scroll the results (using tabs to filter between Upcoming / Past in Events and in between different genders and ages in Players)
- you get the idea..
