Abstract

A set of queries from an application executing on a client computing device is obtained. A first database based on the set of queries is searched to select a set of event types. A set of predicted parameters associated with the set of event types is sent to the application. The application includes instructions to obtain a first parameter and the set of predicted parameters via a user interface of the application and generate a message comprising the first parameter and an indicator identifying the set of predicted parameters. The first parameter and the indicator are obtained via the second message. A combined query including the first parameter and the set of predicted parameters is generated in response to obtaining the indicator. A vehicle record from the vehicle database is obtained based on the combined query. Values of the vehicle record are sent to the client computing device.

Dependent claims

A system for reducing network resource utilization comprising a set of memory devices storing instructions and a set of processors configured to execute the instructions, the instructions comprising:

obtaining, via a set of previous vehicle-related web requests, a query sequence comprising queries from a user application executing on a client computing device;
searching an events database based on the query sequence to select an event type sequence comprising a sequence of event nodes, the searching comprising matching each query of the query sequence with an event node of the event type sequence such that 1) a position of the query in the query sequence is the same as a position of the event node in the event type sequence, and 2) the query satisfies a set of criteria associated with the event node;
sending, via a first web response, a set of predicted query parameters associated with a terminal node of the event type sequence to the user application, the user application comprising instructions to:
obtain, via a user interface of the user application, a set of query parameters that is entered by a user, the set of query parameters comprising the set of predicted query parameters;
and
generate an updated set of query parameters for a first web request by replacing, in the first web request, the set of predicted query parameters with an indicator that the set of predicted query parameters was entered into the user interface;
obtaining, via the first web request, the updated set of query parameters and the indicator;
generating a combined query comprising the updated set of query parameters and the set of predicted query parameters in response to obtaining the indicator;
retrieving a set of vehicle records from a vehicle database based on the combined query;
and
sending, via a second web response, a set of identifiers of the set of vehicle records to the client computing device.

8 more elements

One or more non-transitory, machine-readable media storing instructions that, when executed by one or more processors, performs operations comprising:

obtaining a set of queries from an application executing on a client computing device, the set of queries used to retrieve vehicle records from a vehicle database;
searching a first database based on the set of queries to select a set of event types, the searching comprising matching each respective query of the set of queries with a respective event type of the set of event types based on a determination that a respective set of query parameters of the respective query satisfy a respective set of criteria associated with the respective event type;
sending, via a first message, a set of predicted query parameters associated with the set of event types to the application, the application comprising instructions to:
obtain a first parameter and the set of predicted query parameters via a user interface of the application;
and
generate a second message comprising the first parameter and an indicator identifying the set of predicted query parameters as being entered into the user interface, wherein the indicator is used in the second message in lieu of the set of predicted query parameters;
obtaining, via the second message, the first parameter and the indicator;
generating a combined query comprising the first parameter and the set of predicted query parameters in response to obtaining the indicator;
retrieving a vehicle record from the vehicle database based on the combined query;
and
sending, via a third message, values of the vehicle record to the client computing device.

8 more elements

A method comprising:

obtaining a set of event values from an application executing on a client computing device;
searching a first database based on the set of event values to select a set of event types, the searching comprising selecting the set of event types such that each criterion of a set of criteria associated with the set of event types is satisfied by at least one value of the set of event values;
sending, via a first message, a set of predicted query values associated with the set of event types to the application, the application comprising instructions to:
obtain a first query value and the set of predicted query values via the application;
generate a second message comprising the first query value and an indicator that the set of predicted query values is entered into the application;
obtaining, via the second message, the first query value and the indicator;
generating a combined query comprising the first query value and the set of predicted query values based on the indicator;
retrieving a record from a second database based on the combined query;
and
sending, via a third message, a value of the record to the client computing device.
