Let's say I've defined these indexes in pqf.properties on the SRU server: index.marc.020 = 1=7 # ISBN index.marc.035:1 = 1=1211 # OCLC/utility number where first indicator is non-blank index.marc.100:1 = 1=1 # author where first indicator is non-blank I can use the ISBN index to search for records, e.g.: http://apps.appl.cuny.edu:5661/CENTRAL?version=1.1&operation=searchRetrieve&query=marc.020="9780801449437"&startRecord=1&maximumRecords=15 I can also use the author index to search for records, e.g.: http://apps.appl.cuny.edu:5661/CENTRAL?version=1.1&operation=searchRetrieve&query=marc.100:1="Armenteros"&startRecord=1&maximumRecords=15 So why can't I search for records by utility number (035) with a non-blank first indicator? http://apps.appl.cuny.edu:5661/CENTRAL?version=1.1&operation=searchRetrieve&query=marc.035:1="ebr10488669"&startRecord=1&maximumRecords=15 If you're playing along, you'll notice that these all point to the same record. However, when I try to search for it with &query=marc.035:1="<util_num>", I get no results. I thought maybe this was because there's already another 035 field (with blank indicators) that's an OCLC number so I temporarily removed it... but that didn't solve the issue. Anyone have any experience with this? I need to be able to search by 0359# and I can't figure out what I'm doing wrong. I would greatly appreciate some assistance!
