Abstract
Systems and methods are disclosed for efficiently indexing stream data to facilitate full-text search of the stream data. A stream comprises large amount of data, only some of which is deemed useful for full-text search indexing. An administrator can specify an indexing specification for a stream. The indexing specification can specify one or more sub-streams within the stream for indexing, and/or specify one or more time intervals of stream data for indexing. A query against the stream can specify the indexing specification to use to index the stream before returning results for the query. The query can alternatively specify an indexing specification to apply to a previously indexed stream. Full-text search indexes generated using an indexing specification can return results that are more relevant to a user because the results are more narrowly focused than an index of, e.g., the entire stream.
