Some more elaborate limits can be added to what matches using any of these
functions:
-* "`link(page)`" - match only pages that link to a given page
+* "`link(page)`" - match only pages that link to a given page (or glob)
* "`backlink(page)`" - match only pages that a given page links to
* "`creation_month(month)`" - match only pages created on the given month
* "`creation_day(mday)`" - or day of the month
was created
* "`created_before(page)`" - match only pages created before the given page
was created
+* "`user(name)`" - only available in page subscription preferences, match
+ only changes made by this user
For example, to match all pages in a blog that link to the page about music
and were written in 2005:
blog/* and link(music) and creation_year(2005)
+Note the use of "and" in the above example, that means that only pages that
+match each of the three expressions match the whole. Use "and" when you
+want to combine expression like that; "or" when it's enough for a page to
+match one expression. Note that it doesn't make sense to say "index and
+SandBox", since no page can match both expressions.

More complex expressions can also be created, by using parentheses for
grouping. For example, to match pages in a blog that are tagged with either
of two tags, use:
