Matchtext for multiple words

[Brian Yennie]

Jacque,

I think the "in any order" part will make a single RegEx a nightmare  
(although it's probably technically possible).
How about using something simple like (or scroll down for a non-RegEx  
idea)

".*(dinosaur|dog|cat).*"

Then capture the actual text matched, and remove that from the  
expression. So in your example, you would first match "dinosaur".  
Then you would run the RegEx again as:

".*(dog|cat).*"

Which would match "cat".

Then finally:

".*dog.*"

If you're not married to RegEx, you could just do something like  
this. It should be pretty speedy, as it uses array lookups, simple  
comparisons, and only one pass through your text.

## put the words into an array for quick lookup

repeat for each word w in wordList
    put 0 into myWords[w]
end repeat

## loop through your text and mark all of the words you find

repeat for each word w in myText
   if (myWords[w] = 0) then
     put 1 into myWords[w]
   end if
end repeat

## check that all of your words were "marked" with a 1

put TRUE into foundThemAll
repeat for each word w in wordList
    if (myWords[w] <> 1) then
      put FALSE into foundThemAll
      exit repeat
   end if
end repeat
