Systems, methods and computer program products associated with a flight search engine for searching itineraries between an origin and a destination on a given date, according to a predefined display policy. Available routes may be filtered according to a first set of predefined criteria associated with the routes. The filtered available routes may be ranked according to a second set of predefined criteria. Itineraries may be constructed that are associated with the filtered available routes. The constructed itineraries may be filtered according to a third set of predefined criteria, and the filtered itineraries may be ranked according to a fourth set of predefined criteria. Historical booking data regarding previously booked itineraries for future travels may be received and analyzed, and may be taken into in the ranking of the filtered available routes and the filtered itineraries.

Engine for searching itineraries

A database system includes an original data source storing pieces of original data and a cache source storing pieces of cached data, each associated with an accuracy value. A method of processing queries in the system includes: for each randomly selected client query, retrieving a first piece of cached data matching the query, and retrieving a first piece of original data matching the query; for non-selected client queries, retrieving a second piece of cached data matching the query; evaluating the accuracy value of the second piece of cached data; if the accuracy value is below a given threshold, retrieving a second piece of original data matching the query, and updating the second piece of cached data by the second piece of original data; and adapting a probabilistic model based on the first piece of cached data and the first piece of original data using a machine learning algorithm.
