Perhaps you should try some spelling variations:
"i largest decrease" » "i largest decreases" (Expand Search), "i larger decrease" (Expand Search), "i marked decrease" (Expand Search), "_ largest decrease" (Expand Search), "i large decrease" (Expand Search)
"i values decrease" » "i values increased" (Expand Search), "_ values decrease" (Expand Search)
"au_ rate increased" » "au_ greater increase" (Expand Search), "_ rate increased" (Expand Search), "a rate increased" (Expand Search), "ae rate increased" (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: "((((\"i values decrease\") OR (\"au_ rate increased\"))) OR (\"i largest decrease\"))~".
• Removing quotes may allow a broader search: (((( i values decrease ) OR ( au_ rate increased ))) OR ( i largest decrease ))~.
• Adding a wildcard symbol may retrieve word variants: (((("i values decrease") OR ("au_ rate increased"))) OR ("i largest decrease"))*.
