Underlying Altium Designer's schematic and PCB editors is a powerful query engine. By entering queries into this engine you can logically scope precisely those objects you require.

A query is a string you enter using specific keywords and syntax, which will return the targeted objects. There are many keywords available, allowing you to target objects by their type, their properties, or both.

For a detailed overview of using the query language, see Working with the Query Language.

This reference page details the query language keywords available when searching for file-based components in Altium Designer. For help on a specific query keyword, use the following collapsible sections or highlight (or click inside) any given keyword - in the Query Helper.

To access the component and library query functions, click the Helper button found in the File-based Libraries Search dialog.
