Perhaps you should try some spelling variations:
"preliminary conversations" » "preliminary conservation", "preliminary considerations", "preliminary contemplations", "preliminary observations", "preliminary constructions"
"preliminary conversation" » "preliminary consideration", "preliminary observation", "preliminary construction"
"imaginary conversation" » "imaginary conversations"
"imaginary confessions" » "imaginary conversations", "imaginary expressions", "imaginary companions"

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: (("imaginary confessions") OR ((((("imaginary conversation") OR ("preliminary conversation"))) OR ("preliminary conversations")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"imaginary confessions\") or (((((\"imaginary conversation\") OR (\"preliminary conversation\"))) or (\"preliminary conversations\"))))".
• Removing quotes may allow a broader search: (( imaginary confessions ) or ((((( imaginary conversation ) OR ( preliminary conversation ))) or ( preliminary conversations )))).
• Adding a wildcard symbol may retrieve word variants: (("imaginary confessions") or ((((("imaginary conversation") OR ("preliminary conversation"))) or ("preliminary conversations"))))*.
