  This class is not Zope specific, and can be used in any python
  program to build catalogs of objects.  Note that it does require
  the objects to be Persistent, and thus must be used with ZODB3.

  uid -> the (local) universal ID of objects
  path -> the (local) path of objects

250 251
  If you pass it a keyword argument which is present in sql_catalog_full_text_search_keys
  (in catalog properties), it does a MySQL full-text search.
252 253 254
  Additionally you can pass it a search_mode argument ('natural', 'in_boolean_mode'
  or 'with_query_expansion') to use an advanced search mode ('natural'
  is the default).
255 256 257
  search_mode arg can be given for all full_text keys, or for a specific key by naming
  the argument search_mode_KeyName, or even more specifically, search_mode_Table.Key
  or search_mode_Table_Key
