CV-Search multiple keywords

[Robin481]

The CV-Search somehow allows multiple keywords to be searched for but doesn't handle it very elegantly.

Best for the user might be to allow the user to enter several keywords seperated by ; or similar. Currently when finding search results with multiple terms the search then kind of breaks and just displays an empty button for the found in value. Additionally, when searching for let's say Game Design and Blender this yields people with these two things mentioned in their profile )with the above caveat). When we then add some random nonsense like awueq0w this should give us no more search results, in contrast to that the result however stays even though it probably shouldn't anymore.

TODO:

• [ ] Make CV multiple term search more accessible
• [ ] Match several terms properly over the user
• [ ] Allow the user to clearly enter several different terms via seperation by ;
• [ ] Tests
