Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java slippery" » "python using data slippery", "python using java slippers"
"nhu cac van snippets" » "nhu cau van snippets", "ngu cac van snippets", "nhe cac van snippets", "nhu cac dan 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 slippery\") OR (\"nhu cac van snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java slippery ) OR ( nhu cac van snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java slippery") OR ("nhu cac van snippets"))) OR ("locating bug core snippets"))*.
