It depends a bit on your definition of the term 'word' in this context.

The straightforward solution is to do a replace in the htmlText of the field, wrapping it with a font tag - but this simply hilites every occurence of the search string, rather than the whole word:
##
put the htmlText of field "Data" into tHtmlText
replace "foo" \
    with "<font bgcolor=" & quote & "yellow & quote & ">foo</font>" \
    in tHtmlText
set the htmlText of field "Data" to tHtmlText
##

If you're looking to hilite only complete words, your best option is the wordOffset function and a loop:
##
put the text of field 1 into tText
set the wholeMatches to true
put wordOffset(tWordToFind, tText) into tWordOffset
put 0 into tPrevOffset
repeat until tWordOffset = 0
  add tWordOffset to tPrevOffset
  set the backgroundColor of word tPrevOffset of field 1 to "yellow"
  put wordOffset(tWordToFind, tText, tPrevOffset) into tWordOffset
end repeat
##
If you leave the 'wholeMatches' local property at its default value of 'false' the above script hilites the entire word, if part of it matches tWordToFind.
