Techniques for graphically representing an input query are described in various implementations. In one example implementation, a method that implements the techniques may include receiving, in an electronic discovery computing system and from a user interface, an input query that includes a Boolean expression for identifying documents in a document repository of the electronic discovery computing system. The method may also include parsing the input query to identify terms and operators included in the input query, and generating a graphical representation of the input query that shows how the terms and operators are interpreted by the electronic discovery computing system. The method may also include causing the graphical representation to be displayed via the user interface.
