There was a question in the #solr IRC channel about creating a custom document router to assign documents to shards based on geolocation data.
Looking into this, I think I see a roadblock or two standing in the way of users creating custom router implementations. The "routerMap" field in the DocRouter class is private, and its contents are not dynamically created. It appears that only specific names (null, plain, implicit, compositeId) are added to the map. I'm thinking that if we make routerMap protected (or create protected access methods), and put "static { }" code blocks in each implementation that add themselves to the parent routerMap, it will be much easier for a user to create their own implementation and have it automatically available to use in a CREATE action. Is this worth an issue in Jira? Thanks, Shawn
