comparison gpp/weblinks/search_indexes.py @ 467:b910cc1460c8

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add the ability to conditionally add model instances to the search index on update. This is not perfect, as some instances should be deleted from the index if they are updated such that they should not be in the index anymore. Will think about and address that later.
