Great.  Add that meaning to the glossary entry, please.
(And it's also movement commands, not just search.)

A user seeing the doc string for `C-h S'
(`info-lookup-symbol') can well wonder what "symbol"
means.

My observation comes from someone having questioned
possibly using the word "symbol" in a help menu item
(for `info-lookup-symbol').  The term isn't obvious,
especially for new users.
