-To select a set of pages, such as pages that are locked, pages
-whose commit emails you want subscribe to, or pages to combine into a
-[[blog]], the wiki uses a PageSpec. This is an expression that matches
-a set of pages.
-
-The simplest PageSpec is a simple list of pages. For example, this matches
-any of the three listed pages:
-
- foo or bar or baz
-
-More often you will want to match any pages that have a particular thing in
-their name. You can do this using a glob pattern. "`*`" stands for any part
-of a page name, and "`?`" for any single letter of a page name. So this
-matches all pages about music, and any [[SubPage]]s of the SandBox, but does
-not match the SandBox itself:
-
- *music* or SandBox/*
-
-You can also prefix an item with "`!`" to skip pages that match it. So to
-match all pages except for Discussion pages and the SandBox:
-
- * and !SandBox and !*/Discussion
-
-It's also possible to match pages that link to a given page, by writing
-"`link(page)`". Or, match pages that a given page links to, by
-writing "`backlink(page)`". Or match pages created in a given month, year,
-or day of the month by writing "`creation_month(month)`",
-"`creation_year(year)`" or "`creation_day(mday)`".
-
-For example, to match all pages in a blog that link to the page about music
-and were written on Mondays in 2005:
-
- blog/* and link(music) and creation_year(2005) and creation_day(0)
-
-Matches can also be used to limit matching to pages created before or after
-a given date.
-
-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:
-
- blog/* and (link(tag/foo) or link(tag/bar))
-
-## Old syntax
-
-The old PageSpec syntax was called a "GlobList", and worked differently in
-two ways:
-
-1. "and" and "or" were not used; any page matching any item from the list
- matched.
-2. If an item was prefixed with "`!`", then no page matching that item
- matched, even if it matched an earlier list item.
-
-For example, here is the old way to match all pages except for the SandBox
-and Discussion pages:
-
- * !SandBox !*/Discussion
-
-Using this old syntax is still supported. However, the old syntax is
-deprecated and will be removed at some point, and using the new syntax is
-recommended.
