[Koha] OAI Sets - bug

[Steve Sowder]

I have discovered that if you have a record that is in multiple OAI Sets 
you cannot use the same MARC tag for mapping them.

Thus, if you have two sets with mapping as

590a  is equal to  TOM
590a  is equal to  MARY

And a record with

...
590a  TOM
590a  MARY
...

This record will be in the OAI set "TOM" and it will NOT be in the set 
"MARY".

If you switch the order of the 590a so that

...
590a MARY
590a TOM
...

Then the record will be in the OAI set "MARY" but not in "TOM".

Because the "map reader" stops after the first mapping match.

I consider this a bug.
It should read all of the 590a tags and map each one that is a match.

Don't forget that the MARC tag used in OAI mapping must be an indexed tag.

BTW: This is Koha V3.16.02.000
