Perhaps you should try some spelling variations:
"preliminary conversations" » "preliminary conversation", "preliminary conservation", "preliminary considerations"
"imaginary conversation" » "imaginary conversations", "preliminary conversation"
"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 conversations")))).
• Removing quotes may allow a broader search: (( imaginary confessions ) or ((( imaginary conversation ) or ( preliminary conversations )))).
• Adding a wildcard symbol may retrieve word variants: (("imaginary confessions") or ((("imaginary conversation") or ("preliminary conversations"))))*.
