Applying time-based search phrases across event data

One or more non-transitory computer-readable storage media, storing one or more sequences of instructions, which when executed by one or more processors cause performance of:

• creating a plurality of searchable events from raw time series machine data;
• associating a time stamp with each event of the plurality of searchable events;
• creating two or more time-based persistent data structures for storing the plurality of searchable events, wherein each time-based persistent data structure of the two or more time-based persistent data structures corresponds to a specific time interval, wherein events stored in a particular time-based persistent data structure of the two or more time-based persistent data structures have associated time stamps that fall within a particular time interval corresponding to the particular time-based persistent data structure;
• and
• searching events in the two or more time-based persistent data structures according to a time-based search phrase by parsing the time-based search phrase into multiple sub-search phrases, wherein at least two sub-search phrases of the multiple sub-search phrases are applied sequentially to two or more particular time-based persistent data structures of the two or more time-based persistent data structures in reverse chronological based at least in part on the particular specific time intervals corresponding to the two or more persistent data structures, wherein the two or more time-based particular persistent data structures store events having time stamps that fall within a time interval specified by the time-based search phrase.

An apparatus, comprising:

• an event creator, implemented at least partially in hardware, that creates a plurality of searchable events from raw time series machine data;
• a time stamp processor, implemented at least partially in hardware, that associates a time stamp with each event of the plurality of searchable events;
• a persistent data structure creation device, implemented at least partially in hardware, that creates two or more time-based persistent data structures for storing the plurality of searchable events, wherein each time-based persistent data structure corresponds to a specific time interval, wherein events stored in a particular time-based persistent data structure of the two or more time-based persistent data structures have associated time stamps that fall within a particular time interval corresponding to the particular time-based persistent data structure;
• and
• an event search device, implemented at least partially in hardware, that searches events in the two or more time-based persistent data structures according to a time-based search phrase by parsing the time-based search phrase into multiple sub-search phrases, wherein at least two sub-search phrases of the multiple sub-search phrases are applied sequentially to two or more particular persistent data structures of the two or more persistent data structures in reverse chronological based at least in part on the particular specific time intervals corresponding to the two or more persistent data structures, wherein the two or more particular persistent data structures store events having time stamps that fall within a time interval specified by the time-based search phrase.
