Limit amount of search results

When a user enters a search term that is too generic, slcl would
generate a long list of search results, where this generation could have
a big impact on the server performance and its available resources.

Therefore, it is reasonable to limit the number of search results to an
arbitrary limit, so that users are forced to enter a more specific
search term in order to achieve more relevant results.
