Graphically representing an input query

A system comprising:

• one or more processors;
• a user interface that receives from a user an input query for identifying documents in an electronic discovery document repository;
• a query interpretation engine, executing on at least one of the one or more processors, that identifies terms and operators in the input query and generates a query interpretation that defines how the terms and operators are to be executed against the electronic discovery document repository;
• and
• a query visualization engine, executing on at least one of the one or more processors, that generates a graphical representation of the query interpretation and causes the graphical representation to be displayed via the user interface.

A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, cause the processor to:

• receive, from a user interface, an input query that includes a Boolean expression for identifying documents in an electronic discovery document repository;
• parse the input query to identify terms and operators included in the input query;
• generate a graphical representation of the input query showing how the terms and operators are to be executed by the electronic discovery computing system;
• and
• cause the graphical representation to be displayed via the user interface.
