Question about SOLR custom sort order
Hi, I use Solr 1.4 version and I have a question about SOLR sort order. Requirement : Sort names(e.g. : location names like Dallas(City), las vegas(City), Texas(State), India(Country), Canada(Country), etc..) based on category(e.g. : CITY, STATE, COUNTRY, etc..) How to sort the SOLR results based on custom order? Expected result : 1. Dallas 2. Las Vegas 3. Texas 4. Canada 5. India Thanks Regards, Gupta
Re: Question about SOLR custom sort order
There's no good way of enforcing this as far as I know as you've outlined the problem. You can easily specify multiple sort criteria, where ties in the first criteria are broken by the second criteria and so on. So, if your records have *no* city value you can do what you want by specifying the city field to sortMissingLast then specifying state as your second criteria. So you can probably do what you want by breaking up your location field into fields that are specific for sorting (probably use copyfield here?) and specifying as above.

Re: Question about SOLR custom sort order
We fullfilled a similar requirement by creating a new field that is populated at client-level (a standalone app that converts binary data in solr input documents) Andrea On 1/1/12, Erick Erickson erickerick...@gmail.com wrote: There's no good way of enforcing this as far as I know as you've outlined the problem.
