Some search terms can be written using 「short」 forms, which
consist of a tilde (「~」) followed by a
single character that identifies the term, and finally the arguments (if
any) to the term. For instance, the short form of
is ?name(aptitude)~n aptitude.
When writing a term using its short term, 「whitespace」 -- that
is, space characters, tabs, and so on -- will break the term off and start a
new term. For instance, 「~mDaniel Burrows」
will match any package whose maintainer field contains
「Daniel」 and whose name contains
「Burrows」. To include whitespace characters
in the search expression, you can either place a tilde in front of it (as in
Daniel~ Burrows) or place quotation marks around it (as
in "Debian Project" or even Debian"
"Project). Inside a quoted string, the backslash character
(「\」) can be used to cancel the special meaning of the
quotation mark: for instance, ~d"\"email" will match any
package whose description contains a quotation mark followed immediately by
email. [13]
