concept of TMS Webcore indexeddb ?

HI , it is not so straight forward ,until today ,i still cannot get the indexeddb dataset component works,


let me give u an example , i use JS script to created the indexeddb table ,
     queue_log : "&id,res_id,temp_id,process_type,model_name"

and when my project is running , i can view the queue_log table in the chrome dev console , which
has the table queue_log
with 3 key (key path : 'model_name') primary key( key path: "id" )
                 (key path : 'res_id') primary key( key path: "id" )
                 (key path : 'process_type') primary key( key path: "id" )

and i have other fields , let say is field1string , field2date , not part of the index but normal
fields , what should i do exactly in order to map into the indexeddb component , to use
it the indexeddbDataset component .

thanks .
