Um, maybe it would help if you started out by explaining what you are trying to do instead of changing the requirements after a solution is proposed. The above design seems faulty. If the fields have the same values, there is no way to sort them differently. Boosts are not guaranteed to always promote documents in the desired manner, and will not work with sorting in any case. You can try to kludge things together in various ways, e.g., * Add a prefix so that some fields always sort first, e.g., prefix "aaa..." to a string field to try and ensure that it sorts first * Have not tried this, but it should be possible to use a Solr function query with a function that sorts by the field name: http://wiki.apache.org/solr/FunctionQuery As you seem to be using analysers on the fields, beware that sorting will not work reliably on multi-valued or tokenised fields. You could also index different fields to different Solr cores, fetch the results for individual fields with separate queries, and combine them as desired. This might be the cleanest, if not the most efficient, solution. Regards, Gora
