Description:
I'm having trouble creating an index for OCLC numbers. We already index the number in a direct index called 035 but that indexes any 035 number. I'd like to index only OCLC numbers in their own index since we are buying WorldCat Local.

Here is what I have:

tab00.eng
! 2 3 4 5 6 7 8 9 10 11
!-!!!!!-!!!!!-!-!!-!!-!-!---!!-!!!!!-!!!!!!!!!!!!!!!!!!!!
H OCL IND 24 00 00 OCLC Match on 035$$a(OCoLC)

tab11_ind
! 1 2 3 4 5 6 7 8
!!!!!-!!!!!-!-!!!!!!!!!!-!!!!!-!!!!!!!!!!!!!!!!!!!!-!-!
035 a ocolc OCL -z6

tab_filing
!1 2 3 4
!!-!-!!!!!!!!!!!!!!!!!!!!-!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
! For OCLC match
24 del_subfield
24 to_lower
24 compress -^
24 compress_blank
24 cut_prefix
24 non_numeric

This setup fails to index the OCLC 035’s. The intent of of the tab11_ind entry is to look in the the $$a of the 035 and if it contains the string 'ocolc' then index into OCL and then tab_filing would strip out all non-numeric characters. All it seems to be doing is looking for 035s that contain ONLY the 'ocolc' string and indexes those, which we seem to have 21 of. Is there a way to do what I want?

Resolution:
The 035 field in these OCLC records begins with "(OCoLC)" -- not "ocolc".

Change the abc01 tab11_ind to this:

! 1 2 3 4 5 6 7 8
!!!!!-!!!!!-!-!!!!!!!!!!-!!!!!-!!!!!!!!!!!!!!!!!!!!-!-!

035 a (ocolc)* OCL -z6

(The asterisk is a wildcard indicating that it doesn't matter what comes after.)

Then restart ue_01 and re-send some records for indexing.

If OK, re-run p_manage_05.

I would also note that, since you have this line:

24 non_numeric

there is no need to omit the prefixes in tab11_ind; the non_numeric tab_filing line will omit all non-numeric characters.

KB 16384-36642 is a general discussion of this issue.
