Perhaps you should try some spelling variations:
22occasional letter » occasional letters
occasional letter » occasional writer, occasional verse, occasional notes
2f number » 2 number, 22 number, 21 number
1 numbers » 2 numbers
1 number » a number, 2 number, 3 number

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