+search(spec[, operator])
+
+Search the package database using the indicated search spec.
+The spec may include any of the keywords described in the above list (except 'stable_version' and 'classifiers'), for example: {'description': 'spam'} will search description fields. Within the spec, a field's value can be a string or a list of strings (the values within the list are combined with an OR), for example: {'name': ['foo', 'bar']}. Valid keys for the spec dict are listed here. Invalid keys are ignored:
+name
+version
+author
+author_email
+maintainer
+maintainer_email
+home_page
+license
+summary
+description
+keywords
+platform
+download_url
+Arguments for different fields are combined using either "and" (the default) or "or". Example: search({'name': 'foo', 'description': 'bar'}, 'or'). The results are returned as a list of dicts {'name': package name, 'version': package release version, 'summary': package release summary}
+
+changelog(since)
+
+Retrieve a list of four-tuples (name, version, timestamp, action) since the given timestamp. All timestamps are UTC values. The argument is a UTC integer seconds since the epoch.
