@medit{} uses regular expressions functionality provided by Glib, which in turn uses
@uref{http://pcre.org/, PCRE} library. See
@uref{http://library.gnome.org/devel/glib/stable/glib-regex-syntax.html, Glib manual}
for complete description of regular expression syntax.

Regular expression searches in a document text are limited to single lines, unless the
search pattern includes newline character. For example, pattern "@code{.*}" will match every
line in the document, pattern "@code{.*\n.*}" will match pairs of consecutive lines. This means
that it is mostly impossible to perform searches for text which spawns multiple lines.
