sqlite> create table blah(id integer primary key not null, x text, y integer 
not null);
sqlite> create index blahindex on blah (y);
sqlite> explain query plan select * from blah where y & ? != 0;
0|0|0|SCAN TABLE blah

But other numeric expressions do e.g.

sqlite> explain query plan select * from blah where y = ?;
0|0|0|SEARCH TABLE blah USING INDEX blahindex (y=?)
sqlite> explain query plan select * from blah where y > ?;
0|0|0|SEARCH TABLE blah USING INDEX blahindex (y>?)

Is this a known issue?
