Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"using java java snippets" » "using data java snippets"
"vi dinh xa slippery" » "vi sinh xa slippery", "vi tinh xa slippery", "vu dinh xa slippery", "vi dinh ba slippery", "vi dinh va slippery", "vi binh xa slippery", "vi dinh xa 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: "((((\"vi dinh xa slippery\") OR (\"using java java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( vi dinh xa slippery ) OR ( using java java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("vi dinh xa slippery") OR ("using java java snippets"))) OR ("locating bug core snippets"))*.
