Yes, using mtime is not right -- checking other changes to stat()
might be better.  Of course, we are interested if *content* changes so
a file's mtime, ctime, inode can all change but the contents could
still be exactly the same.

The -N switch checking mtime is fine for the common case where someone
might update a file in place with new contents.  swish-e -h shows:

    -N : index only files with a modification date newer than path supplied
                                 ^^^^^^^^^^^^^^^^^

Using -S prog might be more appropriate way to deal with more complex
situations.  That's what it's for.
