On a quick glance: You're trying to sort on a tokenized field, which is not good. Not good at all. You'll go 'round and 'round and it'll never give you what you want.
Consider your example "Whithers, Alfred Robert" The WhitespaceTokenizer breaks this up into three tokens (I'm ignoring everything but whitespace and lowercase) "whithers", "alfred" and "robert" and puts these tokens in the index. What does sorting on this field mean? Should this be put in Ws? As? Rs? The usual process is to use copyfield and put the input into an un-tokenized field and sort on that field. The stock schema.xml comes with an "alphaOnlySort" that should be a good place to start Best Erick On Wed, Nov 17, 2010 at 11:15 PM, Scott Yeadon <scott.yea...@anu.edu.au>wrote: > Sorry, looks like it was a data-related issue, apologies for the noise > (although if anyone spots anything dodgy in the config feel free to let me > know). > > Scott. > > > On 18/11/10 2:21 PM, Scott Yeadon wrote: > >> Hi, >> >> I'm running solr-tomcat 1.4.0 on Ubuntu and have an issue with the sorting >> of results.
