weird characters in the url

$q could be a serialized array containing your list of and likes ie

Code:

http://test.loc/welcome/index/one+two+three

and in your controller you could convert that to an array

Code:

$q_array = explode('+',$q);

and use that array in your model to loop and create a set of likes
You could extend it to be more dynamic with another segment containing fields.

Code:

http://test.loc/welcome/index/one+two+three/title+content

ie use another array for the fields too.

Code:

$f_array = explode('+',$f);

and combine arrays in model to give you more power


It's up to your requirements
