cloudant - How to combine multiple CouchDB queries into a single request? -

i'm trying query documents in cloudant.com database (couchdb). 2 following query requests work fine separately:

{ "selector": { "some_field": "value_1" } }  { "selector": { "some_field": "value_2" } } 

cloudant's documentation seems indicate should able combine 2 queries single http request follows:

{ "selector": { "$or": [ { "some_field": "value_1" },                           { "some_field": "value_2" } ] } } 

but when try receive following response:

{"error":"no_usable_index",  "reason":"there no operator in selector can used index."} 

can tell me need work?

there doesn't seem way achieve cloudant query @ moment. however, can use view query instead using index created cloudant query. assuming index in design document named ae97413b0892b3738572e05b2101cdd303701bb8:

curl -x post \ 'https://youraccount.cloudant.com/db/_design/ae97413b0892b3738572e05b2101cdd303701bb8/_view/ae97413b0892b3738572e05b2101cdd303701bb8?reduce=false&include_docs=true' \ -d ' {   "keys":[     ["value_1"],     ["value_2"]   ] }' 

this give response this:

{   "total_rows": 3,   "offset": 1,   "rows": [     {       "id": "5fcec42ba5cad4fb48a676400dc8f127",       "key": [         "abc"       ],       "value": null,       "doc": {         "_id": "5fcec42ba5cad4fb48a676400dc8f127",         "_rev": "1-0042bf88a7d830e9fdb0326ae957e3bc",         "some_field": "value_1"       }     },     {       "id": "955606432c9d3aaa48cab0c34dc2a9c8",       "key": [         "ghi"       ],       "value": null,       "doc": {         "_id": "955606432c9d3aaa48cab0c34dc2a9c8",         "_rev": "1-68fac0c180923a2bf133132301b1c15e",         "some_field": "value_2"       }     }   ] }
