Query derived classes with filters

[Paul Boldijar <pa...@3sstudio.com>]

Hey.

I'm using Olingo 4.

I have an entity A, and an entity B, which is derived from A.
I want to get all the B entities.

To do this, I can do

container.getAs().execute(BCollection.class);

or

container.getAs().createSearch(BCollection.class).getResult()

The problem I have, is that I also want to add a filter to my query.

If I add the filter at the end of the queries, there will be 2 requests,
one will query for every B entities, and second will do the filtered query.

What do you think I should try?

Thanks.
