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