The reason for this is not clear at the moment, although we have seen this happening when a partition contains data that for some reason cannot be indexed with the configured Solr schema. Please run on the 'riak attach' console: riak_core_util:rpc_every_member_ann(yz_entropy_mgr, expire_trees, [], 5000). Afterwards exit the console with "Ctrl-G q". The AAE trees should start to be rebuilt shortly after. With default settings, on a cluster with ring size 64 the whole process should finish in about 1 day and any missing but indexable data should appear in all assigned Solr instances. During this time you may still observe inconsistent search results due to the way the coverage query is performed. Keep an eye open for any errors from one of the yz_ modules in the logs during this time. Please let us know if the Search AAE trees can be rebuilt successfully and if this solved your issue.
