Hi,
I want to use HSearch in advanced search in my app. I have a problem with many associated entities:
I have entity apartment, which contains some attributes and some associations.
Searching with apartment's attribute is easy but I don't know how I should search against associated objects.

apartment{
OneToMany Rooms
OneToMany Equipment
OneToMany Properties
OneToMany Reservations
and some other.
}

And my problem is: I want to search apartments, which desriptions/name/city/region contains some text, and they have some rooms, and some equipments, and some properites and apartment is free with given date or range of dates (reservations)

And I should make index with all data, or make index from basic attributes (name,description), search with given attributes, get result (apartment id) and make another hibernate query for associated objects with IN clausule?

Apartment and its associated objects will change rarely, except reservations.

Hi, welcome.
did you see the documentation about @IndexedEmbedded ? it will walk down the refences to the other objects and index the other fields it finds.

yes:) I don't know what is the good way to do what I want. Except reservations all associations may be in index. reservations will change often, so hsearch would rebuild indexes often too.

it's not going to rebuild the full index, only the document relevant to the apartment you change. It shouldn't be a performance problem, I'd try it first and see how it goes. There are many performance-improving options you can tune when you have a good lead test.
