use checkboxgroup to do a search

[Federica_92]

How can I use the checkbox group to set the parameters for a search?
For example:

    var CheckboxGroupView = require("splunkjs/mvc/checkboxgroupview");
    new CheckboxGroupView({
    id: "example-checkboxgroup",
    default: "One",
    el: $("#divToHangOn")
    }).render();

var checkbox[n] = $("#checkbox_id").val()

 var SearchManager = require("splunkjs/mvc/searchmanager");
 new SearchManager({
     id: "search",
    search: "index=main source=checkbox[1] sourcetype=[2] and so on...until n",
    });

new CheckboxGroupView({
    ...
    value: mvc.tokenSafe('$checkboxValue$')
});

new SearchManager({
    ...
    search: mvc.tokenSafe('index=main source=$checkboxValue$')
});
