__build__(query, identifier, preIdentifier) {
    // at the early first call the preBuildHook if exists
    if (_.isFunction(this.__preBuildHook__)){
      query = this.__preBuildHook__.call(this.__builderInstance__, query, identifier, preIdentifier);
    }
    // then check if we have registered helpers to call.
    // If we got no helpers we can only replace the current
    // syntax with the given key and value
    if (this.__registeredHelpers__) {
      // "Shrek": Nobody moves! I've got helpers and I'm not afraid to use them ;-)
      return this._buildWithHelpers(query, identifier, preIdentifier);
    }

    if (_.isPlainObject(query)){
      return this.__buildUnknown__(query, identifier, preIdentifier);
    } else {
