Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java code snippets" » "using data code snippets"
"hang via cua snippets" » "hang va cua snippets", "hang vi cua snippets", "hang giao cua snippets", "hang gia cua snippets", "hang gian cua snippets", "hang giau cua 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 (\"hang via cua snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( hang via cua snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("hang via cua snippets"))) OR ("locating bugs code snippets"))*.
