Hello Alexander, Theodoros and Ludmila,
I also needed that in order to get the records without publication
date (260__c), tried everything but didn't include the 'and', hence
i didn't get the proper results. So, following your suggestion if i
search for "and not year:$->~", I get the correct results!
However, if i replace year (which indexes 260 $c) with 260__c I
also get some strange results... That means "and not 260__c:$->~"
does not work either...
Can you reproduce it? Any ideas?
Now that I've just created the wondeful authorcount index (thanks,
Ludmila!), I can confirm that, at least in our site, "authorcount:0"
seems far more reliable than "and not author:$->~". Inspecting the
results, I haven't seen any false positive for authorcount:0, and
http://ddd.uab.cat/search?f=authorcount&p=0&sc=1 (5,466 hits)
http://ddd.uab.cat/search?p=and+not+author%3A%24-%3E~&sc=1 (94 hits)
So, we are without a generic expression to find missing values. And,
as far as the librarians are concerned, this search is important.
You might be hitting some limitations we've put in place for making sure that
simple user searches don't stress the DB beyond a certain point.
Could you please check the URL bellow (I've added wl=0 - meaning no wildcard
limit) logged in as admin or somebody with cataloguing (bibedit) rights:
http://ddd.uab.cat/search?p=and+not+author%3A%24-%3E~&sc=1&wl=0
Are you still getting only 94 hits?
Cheers,
Ludmila
