Systems and methods for event tracking

A system for event tracking, the system comprising:

• at least one processor;
• and
• at least one memory configured to store instructions that, when executed by the at least one processor, cause the at least one processor to perform operations, the operations including:
• obtaining a query that indicates a query compound hash and/or query parameters;
• executing a query of a search data structure based on the query compound hash and/or query parameters, wherein executing the query includes at least:
• (i) comparing a query spacetime hash with a plurality of spacetime hashes of the search data structure;
• and (ii) comparing a query topic hash with a plurality of topic hashes of the search data structure,
• wherein the search data structure is configured to (a) group the plurality of spacetime hashes into subsets and (b) structure the plurality of topic hashes in vectors or groups of subsets,
• the search data structure is configured to point to a plurality of records associated with a plurality of compound hashes that comprise the plurality of spacetime hashes and the plurality of topic hashes,
• a first compound hash includes a first spacetime hash and a first topic hash for a first event,
• the first spacetime hash is generated based on first time-and-geolocation data for the first event, and
• the first topic hash is generated from first topic data for the first event;
• and
• in response to the query returning at least one match, transmitting event content based on the at least one match.
