Searching Filter

Hi all,
I have this scenario:
lets say that I have meta-data which belong to particular web site and it is stored in index.
This meta-data could have one of these values (0,1,2,3,4,5) and lets say it is a rating of the site
( popularity ).

Now lets say I would like to get search results according to the relevancy but only for whose web sites which has popularity 5 or 4 or 3 only!

How can I achieve that?

Any ideas?

Thanks.
Regards,
Milan

Thanks to all who replied on my question.

The solution is RangeQuery.

Cheers,

Milan

This is a second example of the problem.

Let's say I indexed web sites and I have a field category.

How to get result only from category 2 and 3?

Thanks.

Milan

p.s.: in SQL we can do that really simple:
- select * from table where categoryId in ( 2,3);
or
- select * from table where categoryId=2 or categoryId=3;
