//TODO: Should works also for queries that are pure Hql and not only for ContentManager queries
//Options:
// 1. Use QueryPickerPart that has the ability to configure HqlQueries
// However QueryPickerPart and HqlQueries need some improvements:
// a. Use of parameters instead of string substitution
// b. QueryPickerPart is not attachable
// c. QueryPickerPart does not support pagination by now
// d. QueryPickerPart does not support pure Hql queries because under the hood it uses a ContentQuery
// e. We should have a way to call a razor view in order to show results of the query
// 2. Use DynamicProjectionPart
// a. Firing only the Hql filter if exists otherwise it return null
// b. this approach is the most easy but also the worst because we have queries that will throw exceptions if used by projectionpart or the ProjectionManager
// c. using this approach we could use the laout of the query to customize the result view
// 3. Use a text tokenized as query
// a. Use of parameters instead of string substitution
// b. We should have a way to call a razor view in order to show results of the query
