Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"using java java snippets" » "using data java snippets"
"hai trong va snippets" » "tai trong va snippets", "bai trong va snippets", "dai trong va snippets", "hai trong van snippets", "hai trong ca snippets", "hai trong cac 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 (\"hai trong va snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( using java java snippets ) OR ( hai trong va snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java java snippets") OR ("hai trong va snippets"))) OR ("locating bug core snippets"))*.
