Perhaps you should try some spelling variations:
"value 4 ratio" » "value _ ratio", "value a ratio", "value 4 radio", "value 4 rating"
"value 2 ratio" » "value _ ratio", "value 3 ratio", "value 2 radio"
"value 5 ratio" » "value _ ratio", "value 3 ratio", "value 6 ratio", "value 5 radio"

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: (((("value 4 ratio") OR ("value 2 ratio"))) OR ("value 5 ratio")).
• Removing quotes may allow a broader search: (((( value 4 ratio ) or ( value 2 ratio ))) or ( value 5 ratio )).
• Adding a wildcard symbol may retrieve word variants: (((("value 4 ratio") or ("value 2 ratio"))) or ("value 5 ratio"))*.
