Test case info:

Test uses employee data set:
-documents are structured as

{"name": name<string>, "join_yr" : year<int>, "join_mo" : month<int>, "join_day" : day<int>, "email": email<string>, "job_title" : title<string>, "type" : type<string>, "desc" : desc<tring>}

Steps to repro:
1. Start load data
2. wait data for persistence
3. start rebalance in
4. stop rebalance
5. Start querying

Views structure are:
Views : ['test_view-cf7bcea : map_fn=function (doc)

{ if(doc.job_title !== undefined) emit([doc.join_yr, doc.join_mo, doc.join_day], [doc.name, doc.email] ); }, reduce_fn=None', 'test_view-78dccba : map_fn=function (doc) { if(doc.job_title !== undefined) { var myregexp = new RegExp("^UI "); if(doc.job_title.match(myregexp)){ emit([doc.join_yr, doc.join_mo, doc.join_day], [doc.name, doc.email] );}}}, reduce_fn=None', 'test_view-e734891 : map_fn=function (doc) { if(doc.job_title !== undefined) { var myregexp = new RegExp("^System "); if(doc.job_title.match(myregexp)){ emit([doc.join_yr, doc.join_mo, doc.join_day], [doc.name, doc.email] );}}}, reduce_fn=None', 'test_view-dd0c1b0 : map_fn=function (doc) { if(doc.job_title !== undefined) { var myregexp = new RegExp("^Senior "); if(doc.job_title.match(myregexp)){ emit([doc.join_yr, doc.join_mo, doc.join_day], [doc.name, doc.email] );}}}, reduce_fn=None', 'test_view-68a80d8 : map_fn=function (doc) { if(doc.job_title !== undefined) emit([doc.join_yr, doc.join_mo, doc.join_day], [doc.name, doc.email] ); }

, reduce_fn=_count', 'test_view-d7ada31 : map_fn=function (doc, meta) { if(doc.job_title !== undefined) { var myregexp = new RegExp("^System "); if(doc.job_title.match(myregexp))

{ emit([doc.join_yr, doc.join_mo, doc.join_day], [doc.name, doc.email] );}

}}, reduce_fn=None']
