Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java slippers" » "python using data slippers", "python using java slippery", "python using java grippers"
"phap cong 3 snippets" » "phan cong 3 snippets", "pham cong 3 snippets", "phap phong 3 snippets", "phap cong _ snippets", "phap cong o snippets"

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 slippers\") OR (\"phap cong 3 snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java slippers ) OR ( phap cong 3 snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java slippers") OR ("phap cong 3 snippets"))) OR ("locating bug core snippets"))*.
