US Patent 11907271 Distinguishing between fields in field value extraction

First one or more values are extracted from a plurality of events using a first extraction rule. The extracted first one or more values are assigned to a first field of the plurality of events as a first set of field-data item pairs and a field label is assigned to the first field. Second one or more values and a field label corresponding to the second one or more values are extracted from the plurality of the events using a second extraction rule, where the extracted field label corresponds to the assigned field label of the first field. The extracted second one or more values are assigned to a second field of the plurality of events as a second set of field-data item pairs, thereby distinguishing the extracted second one or more values from the extracted first one or more values.
