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

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"occasional poems, occasional prayers\") OR (\"occasional drivers, occasions written\"))".
• Removing quotes may allow a broader search: (( occasional poems, occasional prayers ) OR ( occasional drivers, occasions written )).
• Adding a wildcard symbol may retrieve word variants: (("occasional poems, occasional prayers") OR ("occasional drivers, occasions written"))*.
