#: * `search`, `-S`:
#: Display all locally available formulae for brewing (including tapped ones).
#: No online search is performed if called without arguments.
#:
#: * `search` [`--desc`] (<text>|`/`<text>`/`):
#: Perform a substring search of formula names for <text>. If <text> is
#: surrounded with slashes, then it is interpreted as a regular expression.
#: The search for <text> is extended online to some popular taps.
#:
#: If `--desc` is passed, browse available packages matching <text> including a
#: description for each.
#:
#: * `search` (`--debian`|`--fedora`|`--fink`|`--macports`|`--opensuse`|`--ubuntu`) <text>:
#: Search for <text> in the given package manager's list.
