Perhaps you should try some spelling variations:
"i values increased" » "i cases increased" (Expand Search), "i also increased" (Expand Search), "i rate increased" (Expand Search), "_ values increased" (Expand Search)
"i largest decrease" » "i largest decreases" (Expand Search), "i larger decrease" (Expand Search), "_ largest decrease" (Expand Search), "i large decrease" (Expand Search)
"b marked decrease" » "b marked increase" (Expand Search), "_ marked decrease" (Expand Search), "a marked decrease" (Expand Search), "_ market decrease" (Expand Search)

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("i values increased") OR ("i largest decrease"))) OR ("b marked decrease"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"i values increased\") OR (\"i largest decrease\"))) OR (\"b marked decrease\"))".
• Removing quotes may allow a broader search: (((( i values increased ) OR ( i largest decrease ))) OR ( b marked decrease )).
• Adding a wildcard symbol may retrieve word variants: (((("i values increased") OR ("i largest decrease"))) OR ("b marked decrease"))*.
