[Koha] Import matching rule for 001 tag

[Cab Vinton]

I'm having trouble getting this to work with the following settings:

Search index: Control-number
Score:  101
Tag: 001
Subfields: [blank]
Offset: 0
Length: 0 [blank does not work either]
Normalization rule: Control-number

I found an old post from Galen suggesting that that the Length
parameter be changed, but since OCLC numbers come in varying lengths
(7,8,9 digits?), I'm not sure how this would work.

Any thoughts? (And yes, I'm aware that the 001 tag is not fool-proof.
In this case, however, it suits our purposes well.)

Many thanks!
