Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets", "using java core snippets", "using java code slippers"
"phan thuc anh snippets" » "nhan thuc anh snippets", "phap thuc anh snippets", "pham thuc anh snippets", "phan thuc hanh snippets", "phan thuy anh snippets", "phan thu anh snippets", "phan thuc anh slippers"
"locating bug code snippets" » "locating bug core snippets", "locating bug code slippers", "locating bung code snippets", "locating bugs code 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 code snippets\") OR (\"phan thuc anh snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( phan thuc anh snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("phan thuc anh snippets"))) OR ("locating bug code snippets"))*.
