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