Perhaps you should try some spelling variations:
22advisory committees » advisory committees, advisory committee
25 k » 25 _, 25 1, 25 c
25 a » 2 a, 25 _, 20 a
20 k » 20 _, 20 a, 20 c
5 k » 5 kv

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %22advisory committees %((((((25 k) OR (5 k))) OR (25 a))) OR (((20 k) OR (2 k))))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22advisory committees %((((((25 k) OR (5 k))) or (25 a))) or (((20 k) or (2 k))))%22".
• Adding a wildcard symbol may retrieve word variants: %22advisory committees %((((((25 k) OR (5 k))) or (25 a))) or (((20 k) or (2 k))))%22*.
