1. A computer implemented method, comprising: accessing time stamped events in a data store on a computing device including one or more processors, wherein the set of events are searchable; maintaining a data model that is associated with a set of the time stamped events, wherein the data model defines a schema to apply to the set of the time stamped events, wherein the data model includes one or more sub-models, and wherein each sub-model of the one or more sub-models is associated with a subset of events in the set of the time stamped events, the subset of events being smaller than the set of the time stamped events; causing display of a graphical interface that lists the one or more sub-models of the data model; receiving first input corresponding to a selection of a particular sub-model of the one or more sub-models through the graphical interface; responsive to the first input, narrowing the set of the time stamped events that are searchable to a particular subset of events that is associated with the selected particular sub-model; subsequent to receiving the first input, receiving second input corresponding to criteria for a search query; after receiving the second input, initiating a search that uses the received criteria to evaluate values extracted using an extraction rule or a regular expression from events in the particular subset of events, wherein the extraction rule or the regular expression corresponds to a field in the schema.
7. The method of claim 1 , further comprising searching the particular subset of events based upon the criteria and the schema by at least: identifying a field definition in the schema for the particular sub-model, the field definition defining the field; applying the field definition to the particular subset of events by employing the extraction rule or the regular expression to extract the values for the field from at least the events in the particular subset of events; comparing the criteria to the values extracted for the field.
