I am using Solr 1.3 I have a "solr.RandomSortField" type dynamic field which I use to randomize my results.
I am in a tricky situation. I need to randomize only "certain results" in my Hits. To elaborate, I have a integer field called "category_id". When performing a query, I need to get results from all categories and place the ones from SOME_CAT_ID at the top. I achieved this by populating a separate dynamic field while indexing data. i.e When a doc is added to the index a field called "dynamic_cat_id_SOME_CAT_ID" is populated with its category id. While querying, I know the value of SOME_CAT_ID, so adding a "sort=dynamic_cat_id_SOME_CAT_ID asc, score desc" to my query, works absolutely fine. So far so good. I am now supposed to randomize the results for category_id=SOME_CAT_ID, i.e results at the top. My understading is that adding "sort=dynamic_cat_id_SOME_CAT_ID asc, *my_dynamic_random_field_SOME_SEED asc*, score desc" to the query would randomize all the results. This is not desired. I only want to randomize the one's at the top (category_id=SOME_CAT_ID), rest should be ordered based on relevance score. Two simple questions: 1. Is there a way to achieve this without writing any custom code? 2. If the answer to #1 is "no", the Where should I start? I glanced the RandomSortField class but could not figure out how to proceed. Do I need to create a custom FieldType? Can I extend the RandomSortField and override the sorting behaviour? Any help would be appreciated. Cheers Avlesh
