1. A method for integrating semantic search, query, and analysis across data sets associated with a plurality of monitored physical assets, the method comprising: presenting, via a graphical user interface, an input field for a search engine that accesses, in a single search, a plurality of indexes generated from data sets associated with a plurality of monitored physical assets, wherein the search engine accesses, in the same single search, run-time data and design-time data of a model of a monitored physical asset of the plurality of monitored physical assets, wherein the design-time data comprises graph-database elements comprising one or more model templates used to define the monitored physical asset, wherein a model template includes one or more attributes of the monitored physical asset including properties associated with the monitored physical asset, and wherein the run-time data comprises specific properties for the monitored physical asset implemented from the one or more model templates; receiving, in the input field of the graphical user interface, one or more search keywords; in response to receiving the one or more search keywords, searching, by a computing device, across the plurality of indexes to determine i) one or more result sets for each of the plurality of indexes having matched portions of the one or more search keywords to the run-time data and ii) one or more result sets having matched portions of the one or more search keywords to the graph-database elements of the design-time data; and presenting, via the graphical user interface, i) graphical objects associated with the one or more result sets associated with each matched monitored physical asset of the plurality of monitored physical assets, results associated with one or more matched properties of the run-time data, and results associated with one or more matched properties of the design-time data, and ii) graphical objects associated with one or more filters to refine the searched results.
