Perhaps you should try some spelling variations:
table bay » table back, table 1a, table bgp
table 2a » table 2, table 2.1, table 2.2
table 27 » table 2, table 7, tabelle 27
table 21 » table 2.1, table 1, table 2
table b » table 1, table 2, table 3

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: ((((table bay) OR (table b))) OR (((((table 2a) OR (table 27))) OR (table 21)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((table bay) or (table b))) or (((((table 2a) OR (table 27))) or (table 21))))".
• Adding a wildcard symbol may retrieve word variants: ((((table bay) or (table b))) or (((((table 2a) OR (table 27))) or (table 21))))*.
