[Koha] OCLC Record Matching Rule

[Ian Bays]

Hi Nicole, Savitra,

 From what I have discovered about the search indexing there are two 
configuration files that have an impact on this.  The actual term that 
you search for will be defined in "ccl.properties" and the file 
"record.abs" tells the zebra indexing what data to extract from the MARC 
data.

So conceptually record.abs tells zebra how to fill the search index and 
ccl.properties tells you what you can search for.

Ideally both files should tell a similar story but it is not always so.  
If a field is in record.abs but not in ccl.properties it will be in the 
search index files but you will not be able to search on it, and 
conversely if it is in ccl.properties but not in record.abs you will be 
able to search on it but there will be no data indexed.

I have used "Control-number" in record matching rules which maps to the 
001 MARC tag successfully.
Some searchable tags can be called a nuber of different things - for 
instance you can search for au, aut or Author all of which equate to 
author name.  The following is from delivered ccl.properties:

#Author-name          1003  A personal or corporate author, 100, 110, 
111, 400
#                           or a conference or meeting      410, 411, 
700, 710,
#                           name.  (No subject name         711, 800, 
810, 811
#                           headings are included.)
Author 1=1003 s=pw
au Author
aut 1=1003

So if you are setting up a Record Matching Rule and you want to see if 
the index you choose works then you can search in the simple search box 
for (eg):

Control-number="123456"
or
Control-number:123456
or similar.  If it does not work for data you know to be there then 
check that record.abs puts the data into the search index and 
ccl.properties enables you to search on it.

I have not used a Normalization rule - sorry.

I hope this is helpful.
