Perhaps you should try some spelling variations:
29 number » 9 number, 21 number, 23 number
22 number » 12 numbers, 2.4 number, a number
2 number » a number
1 number » 1 numbers, a number, 3 number
%occasional » %occasion, %occupational

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: (%occasional OR %occasioned) notes %((((((29 number) OR (22 number))) OR (2 number))) OR (1 number)) 1%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(%occasional OR %occasioned) notes %((((((29 number) or (22 number))) or (2 number))) or (1 number)) 1%22".
• Adding a wildcard symbol may retrieve word variants: (%occasional OR %occasioned) notes %((((((29 number) or (22 number))) or (2 number))) or (1 number)) 1%22*.
