## Search Results

The search results are presented in a form of a table. Each table record presents a single method invocation. If you want to see more details about the selected method invocation, just click the method signature and you will get details of the execution stack this method is a member of.&#x20;

If you want to rapidly inspect parameter values associated with selected methods without navigating away from the current view, just click the link in the Parameters column. This feature streamlines debugging and data validation workflows by providing immediate access to detailed parameter information.

All the records are grouped in sections with respect to a parameter value. The value is displayed in a top row that is spanned over all columns. There is another row for each section at the end of the section. This row contains a Span duration value, which is the amount of time that passed between the beginning of the first invocation through the end of the last one.
