Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"vi luong che snippets" » "vi luong code snippets", "vi luong cho snippets", "vi luong chu snippets", "vi duong che snippets", "dai luong che snippets", "van luong che snippets", "hai luong che snippets"
"using java java snippets" » "using data java snippets"

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: "((((\"using java java snippets\") OR (\"vi luong che snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( using java java snippets ) OR ( vi luong che snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java java snippets") OR ("vi luong che snippets"))) OR ("locating bug core snippets"))*.
