Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets"
"trinh thi phi snippets" » "trinh tai phi snippets", "trinh thiet phi snippets", "trinh tu phi snippets", "trinh chi phi snippets", "trinh phi phi snippets", "trinh thi phu snippets"
"locating bug core snippets" » "locating bug code snippets"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("using java code snippets") OR ("trinh thi phi snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"using java code snippets\") OR (\"trinh thi phi snippets\"))) OR (\"locating bug core snippets\"))".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( trinh thi phi snippets ))) OR ( locating bug core snippets )).
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("trinh thi phi snippets"))) OR ("locating bug core snippets"))*.
