How to apply multiple filters in Hibernate?

Question

Java

I have a Product class, and I want to get a selection of Product from the database, applying some filters to them (price, categories, etc.).
At first glance, you can create a method like
List getFilteredProducts(int minPrice,int maxPrice,Set categories,...)
But what if I do not want to specify some parameters (for example, I want to limit only the max price)?

Hello!
After all, in fact, filtering is a search in the database. Accordingly, enable hibernate search. And there already is the possibility of indexing + the ability to set the necessary parameters, filters.

You can also use ElasticSearch.
