Perhaps you should try some spelling variations:
occasional prayers » occasional poems
occasional writer » occasional notes, occasions written
occasional letter » occasional verse, occasional notes
occasional paper » occasional papers, occasional notes, occasional poems

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 paper) OR (occasional writer))) OR (occasional letter))s) OR (occasional prayers)); ((((occasional paper) OR (occasional writer))) OR (occasional letter)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((occasional paper) OR (occasional writer))) or (occasional letter))s) or (occasional prayers)); ((((occasional paper) OR (occasional writer))) or (occasional letter))".
• Adding a wildcard symbol may retrieve word variants: ((((((occasional paper) OR (occasional writer))) or (occasional letter))s) or (occasional prayers)); ((((occasional paper) OR (occasional writer))) or (occasional letter))*.
