merged r30999:r31005 from Zope-2_8-branch:

- removed all Five dependencies introduced in r30996
  (this fixes the infinite loop issue, but adds redundant interface definitions because we can't use Five's bridging code)

+    A ZCatalog contains arbitrary index like references to Zope

+    of "plug-in" index types.
+
+    Several index types are included, and others may be added.
+
+      Text -- Text indexes index textual content.  The index can be
+      used to search for objects containing certain words.
+
+      Field -- Field indexes index atomic values.  The index can be
+      used to search for objects that have certain properties.
+
+      Keyword -- Keyword indexes index sequences of values.  The index
+      can be used to search for objects that match one or more of the
+      search terms.
+
+      Path -- Path indexes index URI paths. They allow you to find objects
+      based on their placement in a hierarchy.
+
+      Date -- Date indexes index date and type data. They are a type of field
+      index specifically optimized for indexing dates.
+
+      Date Range -- Date range indexes index time intervals. They are designed
+      for efficient searching of dates falling between two boundaries
+      (such as effective / expiration dates).
+
+      Topic -- Topic indexes store prefiltered sets of documents. They are used
+      to optimize complex queries into a single fast query by prefiltering
+      documents by an expression
+
+    The ZCatalog can maintain a table of extra data about cataloged
+    objects.  This information can be used on search result pages to
+    show information about a search result.
+
+    The meta-data table schema is used to build the schema for
+    ZCatalog Result objects.  The objects have the same attributes
+    as the column of the meta-data table.
+
+    ZCatalog does not store references to the objects themselves, but
+    rather to a unique identifier that defines how to get to the
+    object.  In Zope, this unique identifier is the object's relative
+    path to the ZCatalog (since two Zope objects cannot have the same

+        parameters.  You can either pass a mapping to searchResults as
+        the variable 'REQUEST' or you can use index names and search
+        parameters as keyword arguments to the method, in other words::

+          searchResults(title='Elvis Exposed',

+        query will return any objects that have the title *Elvis
+        Exposed* AND also are authored by *The Great Elvonso*.  Terms
+        that are passed as keys and values in a searchResults() call
+        are implicitly ANDed together. To OR two search results, call
+        searchResults() twice and add concatenate the results like this::
+
+          results = ( searchResults(title='Elvis Exposed') +
+                      searchResults(author='The Great Elvonso') )
+
+        This will return all objects that have the specified title OR
+        the specified author.
+
+        There are some special index names you can pass to change the
+        behavior of the search query:
+
+          sort_on -- This parameters specifies which index to sort the
+          results on.
+
+          sort_order -- You can specify 'reverse' or 'descending'.
+          Default behavior is to sort ascending.
+
+          sort_limit -- An optimization hint to tell the catalog how many
+          results you are really interested in. See the limit argument
+          to the search method for more details.
+
+        There are some rules to consider when querying this method:
+
+            - an empty query mapping (or a bogus REQUEST) returns all
+              items in the catalog.
+
+            - results from a query involving only field/keyword
+              indexes, e.g.  {'id':'foo'} and no 'sort_on' will be
+              returned unsorted.
+
+            - results from a complex query involving a field/keyword
+              index *and* a text index,
+              e.g. {'id':'foo','PrincipiaSearchSource':'bar'} and no
+              'sort_on' will be returned unsorted.
+
+            - results from a simple text index query
+              e.g.{'PrincipiaSearchSource':'foo'} will be returned
+              sorted in descending order by 'score'.  A text index
+              cannot beused as a 'sort_on' parameter, and attempting
+              to do so will raise an error.
+
+        Depending on the type of index you are querying, you may be
+        able to provide more advanced search parameters that can
+        specify range searches or wildcards.  These features are
+        documented in The Zope Book.
