Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"nha van van slippery" » "nha lanh van slippery", "nha van ban slippery", "nha tan van slippery", "nha san van slippery", "nha van van 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 snippets\") OR (\"nha van van slippery\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( nha van van slippery ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("nha van van slippery"))) OR ("locating bug core snippets"))*.
