Some more elaborate limits can be added to what matches using these functions:
* "`link(page)`" - match only pages that link to a given page (or glob)
+* "`tagged(tag)`" - match pages that are tagged or link to the given tag (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
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))
+ blog/* and (tagged(foo) or tagged(bar))
Note that page names in PageSpecs are matched against the absolute
filenames of the pages in the wiki, so a pagespec "foo" used on page
