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"
"nha chu van snippets" » "nha cu van snippets", "nha chung van snippets", "nhan chua van snippets", "nha cuu van snippets", "nha chu han 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 (\"nha chu van snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java slippery ) OR ( nha chu van snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java slippery") OR ("nha chu van snippets"))) OR ("locating bug core snippets"))*.
