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