10. An electronic discovery computing system comprising: one or more processors; and one or more memory resources storing instructions that, when executed by the one or more processors, cause the electronic discovery computing system to perform operations comprising: providing a user interface to enable execution of input queries to search for relevant documents in a document repository of the electronic discovery computing system; receiving an input query from a first portion of the user interface, the input query including a number of terms and operators that, when executed via a selectable feature on the user interface, cause the electronic discovery computing system to perform a search in the document repository based on the input query; and while receiving the input query, generating a graphical representation of the input query to be displayed on a second portion of the user interface in real-time, the graphical representation showing how the terms and operators are to be interpreted by the electronic discovery computing system upon execution of the search; wherein generating the graphical representation includes generating a distinct visual indicator for each term operated by a Boolean NOT operator of the input query.
