Abstract: The present disclosure relates to systems and methods for constructing and indexing a rule-based offer database and for generating personalized search results using the same. In one implementation, to construct the database, at least one processor may receive a date rule specifying a start date and an end date, receive a rate rule relating one or more room types to one or more rates, receive a services rule relating one or more services to one or more prices, receive one or more conditions for coupling to the services rule, and construct the database by: associating the one or more conditions with the services rule to generate service entities, linking the date rule to the service entities, associating rates of the rate rule to room types of the rate rule to generate room entities, linking the date rule to the room entities, linking the one or more service entities to the one or more room entities, and indexing the date rule for offer generation.
