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