Perhaps you should try some spelling variations:
"_ fed decrease" » "_ _ decrease" (Expand Search), "_ feed decrease" (Expand Search), "_ ed decrease" (Expand Search)
"_ fe decrease" » "_ _ decrease" (Expand Search), "_ e decrease" (Expand Search)
"45 c decrease" » "45 _ decrease" (Expand Search), "45 _ decreased" (Expand Search), "45 _ decreases" (Expand Search)
"5 a decrease" » "5 _ decrease" (Expand Search), "5 _ decreased" (Expand Search), "5 _ decreases" (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: (("45 c decrease") OR ((("5 a decrease") OR ((("_ fe decrease") OR ("_ fed decrease"))))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"45 c decrease\") OR (((\"5 a decrease\") OR (((\"_ fe decrease\") OR (\"_ fed decrease\"))))))".
• Removing quotes may allow a broader search: (( 45 c decrease ) OR ((( 5 a decrease ) OR ((( _ fe decrease ) OR ( _ fed decrease )))))).
• Adding a wildcard symbol may retrieve word variants: (("45 c decrease") OR ((("5 a decrease") OR ((("_ fe decrease") OR ("_ fed decrease"))))))*.
