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.
