 7.3 Property searches
 =====================
 
 To create sparse trees and special lists with selection based on
 properties, the same commands are used as for tag searches (SeeTag
 searches).
 
 ‘C-c / m  or  C-c \     (org-match-sparse-tree)’
      Create a sparse tree with all matching entries.  With a ‘C-u’
      prefix argument, ignore headlines that are not a TODO line.
 ‘C-c a m     (org-tags-view)’
      Create a global list of tag/property matches from all agenda files.
      SeeMatching tags and properties.
 ‘C-c a M     (org-tags-view)’
      Create a global list of tag matches from all agenda files, but
      check only TODO items and force checking of subitems (see the
      option ‘org-tags-match-list-sublevels’).
 
    The syntax for the search string is described in SeeMatching tags
 and properties.
 
    There is also a special command for creating sparse trees based on a
 single property:
 
 ‘C-c / p’
      Create a sparse tree based on the value of a property.  This first
      prompts for the name of a property, and then for a value.  A sparse
      tree is created with all entries that define this property with the
      given value.  If you enclose the value in curly braces, it is
      interpreted as a regular expression and matched against the
      property values.
