Dear Solr users,
I have two collections C1 and C2
For C1 and C2 the unique key is ID.
ID in C1 are patent numbers normalized i.e US + 12 digits + A1
ID in C2 are patent numbers as I receive them. US + 13 digits + A1 (a leading 0 is added)
My collection C2 has a field name ID12 which is not defined as a unique field.
This ID12 is the copy of the field ID of C1. (US + 12 digits + A1)
Data in ID12 are unique in the whole C2 collection.
Data in C1_ID and C2_ID12 are the same.
I try to request these both collections using shards in the url.
It works fine but I get duplicate documents. It’s normal I know.
Is exists a method, a parameter, or anything else that allows me to indicate
to solr to compare ID in C1 with ID12 in C2 to delete duplicates ?
Many thanks for your help,
