Perhaps you should try some spelling variations:
"c largest decrease" » "c larger decrease" (Expand Search), "_ largest decrease" (Expand Search), "c large decrease" (Expand Search)
"c marked decrease" » "c marked increase" (Expand Search), "_ marked decrease" (Expand Search), "a marked decrease" (Expand Search), "n marked decrease" (Expand Search)
"ic cycles increases" » "six cycles increases" (Expand Search), "50 cycles increases" (Expand Search), "10 cycles increases" (Expand Search), "ic cycles increased" (Expand Search), "ic cycles increase" (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: (((("c largest decrease") OR ("c marked decrease"))) OR ("ic cycles increases"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"c largest decrease\") OR (\"c marked decrease\"))) OR (\"ic cycles increases\"))*".
• Removing quotes may allow a broader search: (((( c largest decrease ) OR ( c marked decrease ))) OR ( ic cycles increases ))*.
