This is indeed an interesting idea so to speak, but I think it's a bit too manual, so to speak, for our use case. I do see it would solve the problem though, so thank you for sharing it with the community! :) -----Original Message----- From: James Thomas [mailto:jtho...@camstar.com] Sent: 15. juli 2013 17:08 To: solr-user@lucene.apache.org Subject: RE: Facet sorting seems weird
Hi Henrik, We did something related to this that I'll share. I'm rather new to Solr so take this idea cautiously :-) Our requirement was to show exact values but have case-insensitive sorting and facet filtering (prefix filtering). We created an index field (type="string") for creating facets so that the values are indexed as-is. The values we indexed were given the format <lowercase value>|<exact value> So for example, given the value "bObles", we would index the string "bobles|bObles". When displaying the facet we split the facet value from Solr in half and display the second half to the user. Of course the caveat is that you could have 2 facets that differ only in case, but to me that's a data cleansing issue.

But given that facet.sort=index just sorts by the faceted index (and I don't want the facet itself to be in lower-case), would that really work?

Then sort on the copyfield.

I am a developer for a company where we recently switched all of our search core from Sphinx to Solr with very great results. In general we've been very happy with the switch, and everything seems to work just as we want it to. Today however we've run into a bit of a issue regarding faceted sort. For example we have a field called "brand" in our core, defined as the text_en datatype from the example Solr core. This field is copied into facet_brand with the datatype string (since we don't really need to do much with it except show it for faceted navigation). Now, given these two entries into the field on different documents, "LEGO" and "bObles", and given facet.sort=index, it appears that LEGO is sorted as being before bObles. I assume this is because of casing differences. My question then is, how do we define a decent datatype in our schema, where the casing is exact, but we are able to sort it without casing mattering? Thank you :) Best regards, Henrik Ossipoff
