AngularJS / Javascript: Find a string match in a nested object -

i have complex object (a user object) has nested arrays , nested objects within it.

i have search filter relatively complicated (checkboxes determining items returned, along search input).

currently search in object so:

for(var key in item){   if(item[key] && item[key].length && string(item[key]).tolowercase().indexof($rootscope.filt.searchfilter.tolowercase()) !== -1){     realsave = true;    } } 

however, works first layer of objects within item; need search objects within objects.

how can this? simpler way above? (note, can't use ng-repeat="item in items | searchfilter" needs parse checkboxes , return values accordingly.

try

realsave = (json.stringify(item).indexof($rootscope.filt.searchfilter.tolowercase()) !== -1) 

(it's long line, scroll right)

it transform whole object single string, can search sub-string you're looking anywhere inside it.
