There are many options available.  One such technique I described in
"Lucene in Action" ... a SecurityFilter.


This SecurityFilter is implementation of the Filter, right?
As I found, the Filter defineds the bits() method, and I should implement some capacities to return set of bits, where first bit means first found document, and if it is set to 1 - document will be shown, otherwise if 0 - it will not
be shown, right?

That is exactly correct. The source code to the SecurityFilter is found in the .zip file you can download from http:// www.lucenebook.com - and it wouldn't hurt our feelings one bit if you bought the book too :)
