-#We're indexing numbers now, and _underscore words

-#Revision 1.5 2002/07/09 04:19:09 richard
-#Added reindex command to roundup-admin.
-#Fixed reindex on first access.
-#Also fixed reindexing of entries that change.

-#More indexer work:
-#- all String properties may now be indexed too. Currently there's a bit of
-# "issue" specific code in the actual searching which needs to be
-# addressed. In a nutshell:
-# + pass 'indexme="yes"' as a String() property initialisation arg, eg:
-# file = FileClass(db, "file", name=String(), type=String(),
-# comment=String(indexme="yes"))
-# + the comment will then be indexed and be searchable, with the results
-# related back to the issue that the file is linked to
-#- as a result of this work, the FileClass has a default MIME type that may
-# be overridden in a subclass, or by the use of a "type" property as is
-# done in the default templates.
-#- the regeneration of the indexes (if necessary) is done once the schema is
-# set up in the dbinit.
-#
-#Revision 1.3 2002/07/08 06:58:15 richard
-#cleaned up the indexer code:
-# - it splits more words out (much simpler, faster splitter)
-# - removed code we'll never use (roundup.roundup_indexer has the full
-# implementation, and replaces roundup.indexer)
-# - only index text/plain and rfc822/message (ideas for other text formats to
-# index are welcome)
-# - added simple unit test for indexer. Needs more tests for regression.
