Joel Bernstein updated SOLR-15132:
----------------------------------
Description:
The *nodes* Streaming Expression performs a breadth first graph traversal. This
ticket will add a *window* parameter to allow the nodes expression to include a
window of time in its traversal.
To take advantage of this feature you must index the content with a String
field which is an ISO timestamp truncated at ten seconds. Then the "window"
parameter can be applied to walk the graph within a specific window of time and
perform aggregations.
Here is an example using Solr logs to answer the following question: What types
of log activities occurred within a 30 second window prior to a window of slow
queries:
