Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"nhat vo van slippers" » "nhat ve van slippers", "nhat so van slippers", "nhat vu van slippers", "nhat vo van slippery", "nhat vo van grippers"

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 (\"nhat vo van slippers\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( nhat vo van slippers ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("nhat vo van slippers"))) OR ("locating bug core snippets"))*.
