string search from list of keywords

#Caché #ObjectScript

anyone know of a simple way to search a blob of text from a list of keywords in one fell swoop, without having to iterate through each keyword and perform an individual search? Ex.

s keywords="This,blob,text"

s text = "This is a sample blob of text"

i text[keywords w "hit"
