Hi all: I was getting 0 results when I should've been getting 78 results with the following query: Host-item:Criminology and criminal justice : an international journal I looked in the Zebra logs, and noticed that it was being transformed into the following: @not @and @attr 1=1033 Criminology @and @and @and @and @and criminal justice = an international journal @attr 1=9011 1 If we decompose the RPN, we'll see that it's basically saying: (Host-item=Crimology and ((((criminal and justice) and = ) and international) and journal )) not Suppression=1 The problem is that "=" is going to return 0 results, so the "and" will always be 0. The way to remedy this problem is to add quotes around our Host-item "value": Host-item:"Criminology and criminal justice an international journal" This will produce the following RPN query, which returns 78 results: @not @attr 1=1033 "Criminology and criminal justice = an international journal" @attr 1=9011 1 As far as I can tell, the = symbol is ignored. You can remove it or substitute another symbol and it'll still return the same number of results. Although it looks like using * for truncation doesn't work in double quotation marks... I suppose that's because it's already part of a term so you can't really translate it into RPN separately. I notice sometimes we strip out double quotation marks from queries and sometimes we add them in. we should probably do something consistent.
