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 van slippers" » "vi trinh van slippers", "vi sinh vat slippers", "vi sinh van slippers", "vi tinh van slippers", "vu dinh van slippers", "vi dinh van slippery", "vi dinh 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: "((((\"vi dinh van slippers\") OR (\"using java java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( vi dinh van slippers ) OR ( using java java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("vi dinh van slippers") OR ("using java java snippets"))) OR ("locating bug core snippets"))*.
