Abstract
Performing a search over a trace of program execution. A method includes receiving a search expression including one or more search criteria. The search expression is targeted at one or more trace data streams storing a trace of program execution. Based on the one or more search criteria, a plurality of families of code entity invocations are identified. Each family identifies a plurality of code entity invocations that are related to each other, and that are identified based in on one or more trace data streams. A ranking among the plurality of families of code entity invocations is identified, and based at least on the ranking a set of code entity invocations determined to meet the one or more search criteria is returned. The set of code entity invocations is ordered by a relevance determined based at least on the ranking among the plurality of families.
