Perhaps you should try some spelling variations:
"occasional prayers; occasional letter" » "occasional poems; occasional letter", "occasional writer; occasional letter", "occasional prayers; occasional writer"
"occasional prayers; occasional verse" » "occasional poems; occasional verse", "occasional writer; occasional verse"
"occasional notess; occasional notes" » "occasional notices; occasional notes", "occasional poems; occasional notes", "occasion notes; occasional notes"

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 prayers; occasional letter") OR ("occasional prayers; occasional verse"))) OR ("occasional notess; occasional notes")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"occasional prayers; occasional letter\") OR (\"occasional prayers; occasional verse\"))) or (\"occasional notess; occasional notes\"))".
• Removing quotes may allow a broader search: (((( occasional prayers; occasional letter ) OR ( occasional prayers; occasional verse ))) or ( occasional notess; occasional notes )).
• Adding a wildcard symbol may retrieve word variants: (((("occasional prayers; occasional letter") OR ("occasional prayers; occasional verse"))) or ("occasional notess; occasional notes"))*.
