Systems and methods for asynchronous searching and filtering of data

A method, comprising:

• subscribing to a query, via a client component in an automation control and monitoring system, by providing one or more criteria in a subscription request and a limit designating a maximum amount of data to be returned in a notification, to a processor of the automation control and monitoring system;
• receiving, from the processor, a first notification comprising a first portion of data relating to the one or more criteria of the subscription request, wherein the first notification is limited by the designated maximum amount of data;
• and
• receiving, from the processor, one or more additional notifications comprising additional portions of data relating to the one or more search criteria of the subscription request that become available after subscribing to the query, wherein the one or more additional notifications comprise a set of data not sent in the first notification due to the limit and the one or more additional notifications do not exceed the limit.

An automation control and monitoring system, comprising:

• a server comprising a processor;
• a graphical user interface of the automation control and monitoring system;
• a view model configured to request and receive data relevant to the graphical user interface from the processor via a live query, the request comprising a limit designating a maximum amount of data to be returned in a notification;
• and
• a data model comprising a model of objects that the processor accesses, wherein the processor is configured to:
• access the requested data from the data model;
• and
• provide the requested data, including any additions, modifications, or both to the requested data, to the view model via asynchronous notifications to the view model, wherein the requested data is provided according to the limit, such that the requested data does not exceed the limit, by:
• providing multiple notifications that do not exceed the limit, until a full set of the requested data is provided.

An automation control and monitoring system, comprising:

• a client processor of the automation control and monitoring system that provides a subscription request to a server, the subscription request providing one or more criteria and a limit designating a maximum amount of data to be returned in a notification, to the server, wherein the client processor:
• receives a set of data, via a first notification, from the server based upon the one or more criteria in the subscription request, wherein the first notification is limited by the designated maximum amount of data;
• and
• receives, via additional notifications, additional sets of data, modifications to the set of data, or both, when additional data or modifications corresponding to the one or more criteria in the subscription request are available, wherein the additional notifications comprise a set of data not sent in the first notification due to the limit and the additional notifications do not exceed the limit.
