Try something like:

Take the original string, add a leading ' and trailing %'
sFind=['VIBR CHOL BIOV%']

Replace each space with %' $ searchfld or '
sFind=['VIBR%' $ searchfld or 'CHOL%' $ searchfld or 'BIOV%']

Build your SQL string:
s = [select * from theTable where ] + sFind

which gives

select * from theTable where 'VIBR%' $ searchfld or 'CHOL%' $ searchfld or 'BIOV%'

Then execute the contents of s
&s
