When searching for activities, clubs, or users, the current search algorithm uses the OR operation for keywords. For example, if I search for "Marathon Challenge," the results include all activities that contain either "Marathon" or "Challenge," which often leads to a large number of irrelevant results. This can make it difficult to quickly find specific activities or users.

I believe it would be highly beneficial to implement an AND operation for search terms. This change would allow users to narrow down their search results more effectively and find exactly what they are looking for without having to sift through numerous unrelated entries.
