Perhaps you should try some spelling variations:
"aided two" » "aided tool"
"nice text" » "nice sept", "nice et", "nice next", "neine text", "nfine text"
"file text" » "file test", "file tests"
"ice text" » "ice next", "eine text", "fine text"

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: (("aided two") OR ((((("ice text") OR ("nice text"))) OR ("file text"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"aided two\") or (((((\"ice text\") OR (\"nice text\"))) or (\"file text\"))))*".
• Removing quotes may allow a broader search: (( aided two ) or ((((( ice text ) OR ( nice text ))) or ( file text ))))*.
