1. A method comprising: discovering fields in events returned in response to an initial search query, wherein the events comprise portions of raw data, and the fields are defined by extraction rules for extracting values from corresponding portions of raw data; causing display of a graphical user interface (GUI) that enables a user to select or enter criteria for a subset of the discovered fields without entering a search query in a search bar; receiving through a portion of the GUI that does not include a search bar for entering a search query at least one criterion for at least one field from the subset of the discovered fields; and causing, by a processing device, the events returned in response to the initial search query to be filtered based on the received at least one criterion for the at least one field.
