couchdb - Strange error message -

i have defined following view:

{ "_id":"_design/test",   "language":"javascript",   "views":   { "test":      { "map": "function(doc) { (var k in doc.data) emit(doc.data[k],null);}",       "options": {"collation":"raw"}     }   } } 

when querying view without parameters, expected result (sorted "ab...ab" instead of "aabb" because specified raw collation):

http://localhost:5985/test/_design/test/_view/test  {"total_rows":13,"offset":0,"rows":[   {"id":"-","key":"a","value":null},   {"id":"-","key":"b","value":null},   {"id":"-","key":"c","value":null},   {"id":"-","key":"d","value":null},   {"id":"-","key":"e","value":null},   {"id":"-","key":"f","value":null},   {"id":"-","key":"a","value":null},   {"id":"-","key":"b","value":null},   {"id":"-","key":"c","value":null},   {"id":"-","key":"d","value":null},   {"id":"-","key":"e","value":null},   {"id":"-","key":"f","value":null},   {"id":"-","key":"g","value":null} ]} 

i use startkey , endkey ask range between b , a, , expect receive keys bcdefa, instead receive following error message:

http://localhost:5985/test/_design/test/_view/test?startkey=%22b%22&endkey=%22a%22  { "error": "query_parse_error",   "reason": "no rows can match key range, reverse start_key ,               end_key or set descending=true" } 

why no rows can match key range, when rows b,c,d,e,f , match ?

edit: have single document (revision , id omitted):

{ "_id": "-",    "_rev": "-",    "data": [ "a", "b", "c", "d", "e", "f", "a", "b", "c", "d", "e", "f", "g" ]  } 

i can confirm experience same behaviour in version 1.1 on ubuntu 10.04.

to elaborate:

curl http://localhost:5984/test/_design/test/_view/view?startkey=%22b%22\&endkey=%22a%22 

returns error

{"error":"query_parse_error","reason":"no rows can match key range, reverse start_key , end_key or set descending=true"} 

while

curl http://localhost:5984/test/_design/test/_view/view?startkey=%22b%22\&endkey=%22d%22 

gives

{"total_rows":12,"offset":1,"rows":[ 

{"id":"stuff","key":"b","value":null}, {"id":"stuff","key":"c","value":null}, {"id":"stuff","key":"d","value":null} ]}

so quoting issues don't problem.

i using single document:

{ 

"_id": "stuff", "_rev": "2-0507028fcab427a1b28ed6b3d4a6c05e", "data": [ "a", "b", "c", "d", "e", "f", "a", "b", "c", "d", "e", "f" ] }
