+# 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 1.5  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.
