Then there is also this repeat-less approach using arrays and filter:

function findWordOffsets pText, pSearchTerm
        put replaceText(pText,"\W+"," ") into pText
        split pText by space
        combine pText with cr and tab
        filter pText with "*" & tab & pSearchTerm
        sort numeric pText
        return pText
end findWordOffsets

put "Then the quick brown fox jumped over "The" very,

very lazy

red dog on the sofa.” into temp       — note the extra spaces and line breaks.

put findWordOffsets(temp, “the”)   
returns:
2       the
8       The
15      the
