Perhaps you should try some spelling variations:
"a latency decreased" » "a rate decreased" (Expand Search), "_ latency decreased" (Expand Search), "c latency decreased" (Expand Search), "a latent decreased" (Expand Search)
"a largest decrease" » "a largest decreases" (Expand Search), "a larger decrease" (Expand Search), "a marked decrease" (Expand Search), "_ largest decrease" (Expand Search), "a latest decrease" (Expand Search)
"a large decrease" » "a marked decrease" (Expand Search), "a large increases" (Expand Search), "a large degree" (Expand Search), "_ large 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: (((("a largest decrease") OR ("a latency decreased"))) OR ("a large decrease"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"a largest decrease\") OR (\"a latency decreased\"))) OR (\"a large decrease\"))".
• Removing quotes may allow a broader search: (((( a largest decrease ) OR ( a latency decreased ))) OR ( a large decrease )).
• Adding a wildcard symbol may retrieve word variants: (((("a largest decrease") OR ("a latency decreased"))) OR ("a large decrease"))*.
