Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"using java java snippets" » "using data java snippets"
"anh quan va snippets" » "anh quang va snippets", "anh tuan va snippets", "anh xuan va snippets", "anh quan vi snippets", "anh quan ha snippets", "anh luan va 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: "((((\"anh quan va snippets\") OR (\"using java java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( anh quan va snippets ) OR ( using java java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("anh quan va snippets") OR ("using java java snippets"))) OR ("locating bug core snippets"))*.
