Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"phan so van slippery" » "phan bo van slippery", "phan co van slippery", "phap so van slippery", "phan su van slippery", "phan vo van slippery", "phan so 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 (\"phan so van slippery\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( phan so van slippery ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("phan so van slippery"))) OR ("locating bug core snippets"))*.
