Perhaps you should try some spelling variations:
reporting biases » reporting based, reporting base, reporting bias
reporting bises » reporting abuses, reporting based, reporting base
reporting bis » reporting bugs, reporting b, reporting bei

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: "((reporting bis) OR (((reporting bises) OR (reporting biases)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((reporting bis) or (((reporting bises) OR (reporting biases))))".
• Removing quotes may allow a broader search: ((reporting bis) or (((reporting bises) OR (reporting biases)))).
• Adding a wildcard symbol may retrieve word variants: "((reporting bis) or (((reporting bises) OR (reporting biases))))*.
