Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"using data java snippets" » "using java java snippets", "using sat java snippets", "missing data java snippets"
"vi dung trong snippets" » "va dung trong snippets", "vi ung trong snippets", "vi dong trong 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 data java snippets\") OR (\"vi dung trong snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( using data java snippets ) OR ( vi dung trong snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using data java snippets") OR ("vi dung trong snippets"))) OR ("locating bug core snippets"))*.
