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