Perhaps you should try some spelling variations:
"require high coverage" » "requires high coverage" (Expand Search), "require high average" (Expand Search)
"requireds high coverage" » "requiresds high coverage" (Expand Search), "requireds high average" (Expand Search), "requires high coverage" (Expand Search)
"required high coverage" » "requiresd high coverage" (Expand Search), "required high average" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"require high coverage\") OR (((\"requireds high coverage\") OR (\"required high coverage\"))))~".
• Removing quotes may allow a broader search: (( require high coverage ) OR ((( requireds high coverage ) OR ( required high coverage ))))~.
• Adding a wildcard symbol may retrieve word variants: (("require high coverage") OR ((("requireds high coverage") OR ("required high coverage"))))*.
