                  uid='1111',

                    'searchable_text' : u'', 
                            'modified' : datetime.datetime(), 
                            'crated' : datetime.datetime()
                        },
                   data = {}
                  )

-Search
 db.search(parts, ["and",
                       { "filters":
                          "exclude":
                       },

                       [ "or",
                          {"filters":
                           "exclude": },
                          { "filters":
                            "exclude": }
                       ]
                   ]
               )

Doc and Index Relationship
Xapian has three applications: indexes terms, puts data fields in order,
and returns data.

-set/list/tuple: Each includes pair term data
-string/unicode: Uses whole search terms
-data/int/float: Sorts the range
