Features

+ All queries return Q promises
+ Injectors for http and log modules
+ Add custom queries easily

$3

Each function in library return Q promise, no more callbacks!

$3

Use custom http or log module

#### Http module
Inject - es.injector("$http", ...);

Module should expose request(opts) method with Q promise to return resulted response in JSON object

``
//opts structure
{
uri : "http://...", //request uri to elastic search server
method : "get", //get, post or delete http method
json : {}, //json formatted data to server
body : {}, //string data pass to server
}
`

Promise should return response from elastic search server (json formatted)

#### Log module
Inject - es.injector("$log", ...);

Should expose log method similar to standard console.log

#### Custom queries

Add custom query

`
es.queryTemplates.admin_cookies_count_tripled =
parent : "count"
req: (opts) -> #format data to send
bool :
must :
term :
user : "admin"
term :
cookie_type : opts.cookie_type
resp: (res) -> res * 3 #parse data when received

#find!
es.query("admin_cookies_count_tripled", {cookie_type : "chocolate"}).then (cnt) ->
console.log(cnt)

es.query("admin_cookies_count_tripled", {cookie_type : "lemon"}).then (cnt) ->
console.log(cnt)
`

parent property

+ Define another query.req which will be used to format data, after current req formatting.
+ When data received from server they will be passed to previous formatters in chain then result of transformation will be passed to resp` method.

Chain of custom queries could be created as needed.
