Perhaps you should try some spelling variations:
"helped decrease" » "helped decreased" (Expand Search), "helped increase" (Expand Search)
"meet decrease" » "meet decreased" (Expand Search), "meet increase" (Expand Search)
"samir decrease" » "samir decreased" (Expand Search), "samir increase" (Expand Search), "sami decrease" (Expand Search)
"mean decrease" » "mean decreased" (Expand Search), "mean increase" (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: "((((\"helped decrease\") OR (((\"meet decrease\") OR (\"samir decrease\"))))) OR (\"mean decrease\"))~".
• Removing quotes may allow a broader search: (((( helped decrease ) OR ((( meet decrease ) OR ( samir decrease ))))) OR ( mean decrease ))~.
• Adding a wildcard symbol may retrieve word variants: (((("helped decrease") OR ((("meet decrease") OR ("samir decrease"))))) OR ("mean decrease"))*.
