"require high coverage" » "required high coverage" (Expand Search), "requires high coverage" (Expand Search)
"require higher average" » "required higher average" (Expand Search), "requires higher average" (Expand Search)
"requireds high coverage" » "requiredds high coverage" (Expand Search), "requiresds high coverage" (Expand Search), "required high coverage" (Expand Search), "requires high coverage" (Expand Search)

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

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