Claim 1:
2. The non-transitory computer-readable medium of claim 1 storing further instructions readable and executable by at least one electronic processor to perform a retrieval constraint generation method operating on historical log data comprising log events which are time stamped and which are defined by values for the set of fields, the retrieval constraint generation method comprising:
normalizing selected fields of the set of fields in the log pattern to generate at least one normalized log pattern item wherein the selected fields do not include the one or more filter fields;
identifying matching normalized log events that match the at least one normalized log pattern item in normalized log data wherein the normalized log data are generated from the historical log data by normalizing the selected fields in the historical log data; and
generating the at least one additional constraint from values of the one or more filter fields in the matching normalized log events.
