But then, he'll say, he uses grep.

The other disadvantages of command-line tools are: 

- They can't re-use information learned in one scan to make another scan
more efficient.  Indexers index once (and incrementally after) and the
searches run against the indexed data--typically much faster.

- The traditional tools don't understand specialized files.  It doesn't
help much to know that your fedora-list mbox matches a phrase without
knowing which message it is, if you have a few hundred messages.

On the other hand, indexers:

- Use resources in the background, possibly at inconvenient times.

- Take up (possibly significant) disk space with indices.

- Index only what they recognize.

So each method has its good and bad points.
