You can limit the set of events using the base search (the part before the first |). Also, the way transaction works is, it takes a field or fields as arguments to identify all events where those fields match. For example, you may want to group all of the events with the same IP Address, into a single transaction. It will need a common value in order to associate them. The startswith and endswith would be used when there are different events that are happening in a sequence, like, a login, some other stuff happens, then a logout. Another example would be parts of a transaction that could even span different event sources.
Is there a common thread between the 500 error and the error that follows it? I'm guessing IP or host or something?
