Sometimes when I search based on a PID I get multiple requisitions. When I look in the raw data it is not due to the requisition having that ID but more so that the number shows up in similar_pids. How are similar pids determined? What is the criteria for it?
Example:
"similar_pids": [
[removed by moderator] ,
[removed by moderator] ,
[removed by moderator] ,
[removed by moderator] ,
[removed by moderator]
],
