[Koha] Matching rules on record import

[Martin Longo]

Hi there

I'm trying tu get my Koha3 up and running, but need some directions 
setting Matching Rules to import MARC records.

First of all ... Matching rules seems to be working  ok ...  I've used 
the ISBN rule and got good results.... BUT ... there are some problems 
when the records don't have ISBN data (or ISSN) ... so I need a way to 
match those.

for example .. I have this record (already imported into Koha) and when 
I try to import again it has "no match" (of course, because it has no ISBN)

So ... I need advice on how to set up a valid matching rule to handle a 
situation like this one.

The records will come from various libraries (around 13) each one with 
distinctive control numbers (field 001) so I think maybe comparing this 
field and title (field 245$a)  would give me a good enough matching rule.

the problem is ... how to set it up on Koha  :)

Frist thing I don't understand completely ... when creating a new 
matching rule I must specify a "search index" value (on ISBN rule it has 
'isbn'). Now, for something like what I need, what should be the value, 
if it has to be one...

Thanks in advance
