Perhaps you should try some spelling variations:
yeast responses » best responses, plant responses, fast response
host responses » host response
test responses » stress responses, forest responses, root responses
best response » host response, fast response, request response

Try widening your search to All Fields.

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: %wind ((((yeast responses) OR (host responses))) OR (((test responses) OR (best response))))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%wind ((((yeast responses) or (host responses))) or (((test responses) OR (best response))))%22".
• Adding a wildcard symbol may retrieve word variants: %wind ((((yeast responses) or (host responses))) or (((test responses) OR (best response))))%22*.
