javascript - Creating a binding list projection from a list of search terms -

-

i trying create filtered list projection collection of search terms. instance, if have 1 search term, can this:

if (options.groupkey == "filtered") {     this._items = data.getitemsfromgroup(this._group);     var query = windows.storage.applicationdata.current.localsettings.values["filters"];     this._items = this._items.createfiltered(function (item) {         if (item.content.search(query) > -1) {             return true         } else {             return false         }     }) }

but if 'filters' local setting crlf delimited list, this:

cisco microsoft dell

currently, search compare each term 'cisco/nmicrosoft/ndell' won't work. content.search doesn't accept array. should loop in createfiltered function somehow? doesn't seem in spirit of projection. accepted way this?

what storing , object in "filters" settings every filter property? work you?

if (options.groupkey == "filtered") {     this._items = data.getitemsfromgroup(this._group);     var query = windows.storage.applicationdata.current.localsettings.values["filters"];     this._items = this._items.createfiltered(function (item) {         return object.keys(query).indexof(item) > -1;     }) }

the query object follows: 

{      cisco: "",     microsoft: "",     dell: "" }

does make sense?

edit: made little change in code since believe if (query[item]) return false because of javascript type-casting
