To add a missing information to this question:
The query never timeout if we remove "AND tags:(message)" part from it
i.e. a simple query like the one below always succeed.
/select?wt=json&q=to:733d5cb23129734585af7b9fe16b1bbc5daa5b5c
However, as soon as we add AND operator to the query, it starts to timeout.
Also we observed, if there are no documents in the bucket, timeout never
happens even with AND operator,
but as soon as we add even a single document in the bucket, query starts timing
out.
Also, we observed that a simple query lookup over tags only is still timing out:
/select?wt=json&q=tags:message ---> gives us the following response:
The server encountered an error while processing this request:
{error,
{error,
{case_clause,
{{badfun,#Fun},
[{mi_server,iterate,6,[{file,"src/mi_server.erl"},{line,657}]},
{mi_server,lookup,8,[{file,"src/mi_server.erl"},{line,632}]}]}},
[{riak_search_client,search_doc,8,
[{file,"src/riak_search_client.erl"},{line,165}]},

{riak_solr_searcher_wm,to_json,2,
[{file,"src/riak_solr_searcher_wm.erl"},{line,120}]},
{webmachine_resource,resource_call,3,
[{file,"src/webmachine_resource.erl"},{line,169}]},
{webmachine_resource,do,3,
[{file,"src/webmachine_resource.erl"},{line,128}]},
{webmachine_decision_core,resource_call,1,
[{file,"src/webmachine_decision_core.erl"},{line,48}]},
{webmachine_decision_core,decision,1,
[{file,"src/webmachine_decision_core.erl"},{line,532}]},
{webmachine_decision_core,handle_request,2,
[{file,"src/webmachine_decision_core.erl"},{line,33}]}]}}
Any help or pointers in the right direction will be greatly appreciated.
