Angularjs ui-router - pass extras 'unplanned' parameters -

i have simple state :

.state('search', {     url: '/search',     templateurl: 'views/search.html',     controller: 'search' })

and pass unplanned parameters controller when using search state or /search route :

ui-sref="search({foo:1, bar:2})"  // call '#/search?foo=1&bar2',  // match state , pass foo , bar controller (through $stateparams)

when try this, matches otherwise of router instead. :(

i've read lot of solutions imply declare each parameter in state:

.state('search', {     url: '/search?param1&param2&param3?...', })

but cannot far parameters list not defined , changes time depending on searched content.

is there way achieve ? or wrong somewhere ?

thx.

edit : when try call directly url : #/search?foo=1, state search matches foo parameter never goes $stateparams empty. don't know how in.

.state('search', {    params: ['param1','param2','param3'],    templateurl: '...',    controller: '...' });  ui-sref="search({param1:1, param2:2})"
