Ah! Then you want a slightly different Regex pattern.  .*dex.* would
match both lines.

You'll need to be more specific when you say "the word dex" to
determine your regex.

\sdex\s will match dex surrounded by whitespace, which might be what you want.

\bdex\b will match dex surrounded by word boundaries, which is
probably the best pick.
