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