Perhaps you should try some spelling variations:
"chap dat hang slices" » "chap dat ham slices", "phap day hang slices", "cai dat hang slices", "lap dat hang slices", "chap dat khanh slices", "chap dat quang slices", "chap tat thang slices"
"python using java grippers" » "python using data grippers", "python using java slippers"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code snippets", "locating bug core snippets", "locating bug code slippers"

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: "((((\"python using java grippers\") OR (\"chap dat hang slices\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java grippers ) OR ( chap dat hang slices ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java grippers") OR ("chap dat hang slices"))) OR ("locating bug code snippets"))*.
