JavaScript regex returns -1 when > 0 is expected -

okay have following string:

aktiv landbruger / regler al

with string attempt run following regex:

/regler al/i

however once run string.search('/regler al/i')

it returns -1

however when attempt on

so why javascript returning -1

remove single quotes around regex
