Abstract: Methods, systems, and programming for updating a search index are described herein. In a non-limiting embodiment, event data representing actions performed on a plurality of content items managed via the search index may be obtained. The event data may be filtered based on pre-determined criteria to generate updated event data, where the updated event data represents relevant actions performed on at least one of the plurality of content items and are associated with the search index. An updated search index based on the updated event data may then be generated.
