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

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 writers, occasional writer\") OR (\"occasional papers, occasional poems\"))".
• Removing quotes may allow a broader search: (( occasional writers, occasional writer ) OR ( occasional papers, occasional poems )).
• Adding a wildcard symbol may retrieve word variants: (("occasional writers, occasional writer") OR ("occasional papers, occasional poems"))*.
