given an object

{"a":{"b":false}}

I expect "$..*[?(@ === false)]" to return a result, in fact, this search returns empty array

As far as I can tell, the issue is on line 674:

JSONPath.prototype._eval = function (
    code, _v, _vname, path, parent, parentPropName
) {
    if (!this._obj || !_v) { return false; }

because _v === false the expression nether evaluated
