here you can play with boost

you can also play with numbers to achieve best results.
this is first solution I've thought about(I mean there may be more efficient
solutions)

string query should look like: "+includes:(red frogs) -excludes:(red frogs)"

Hi,
The best way to determine bottlenecks is profiling. (JProfiler is very
good tool for that. It's commercial product with free evaluation)
I was indexing 1.5 million documents in 45 minutes.
before optimizing it took much more time to index. optimization was done
through 'select' query changin
maybe it is not the best solution, but
you can form restriction clause like (+allowedRole1 +allowedRole2
+allowedRole2 -forbiddenRole1 -forbiddenRole2 ... -forbiddenRoleN)
where (forbiddenRole1 ... forbiddenRoleN) are all posible roles except
allowed roles.
