[Map] Search by concept, resource, hashtag

[xuanqiz]

User story: The user opens the map, and wants to find a specific concept or resource title to check its location.

• [ ] Add the search bar at the top of the map.

When a certain resource is sought for:

• [ ] Highlight with color the concept(s) on the map as google maps does:

• [ ] Let the name of the concept(s) appear

• [ ] Make the corresponding resource(s) appear below the map

• [ ] Optional but cool: when the search is done for a specific ressource, let it appear on the map like this:

• [ ] if no resource found for the specific title, message "No resource found."

• [ ] if no concept found, a message "No concept found."

• [ ] if no concept nor resource found, a message "No concept nor resource found."
