Perhaps you should try some spelling variations:
"vi hanh va snippets" » "vi thanh va snippets", "va hanh va snippets", "ve hanh va snippets", "vi hang va snippets", "vi hanh vi snippets", "vi hanh va slippers"
"using a java snippets" » "using _ java snippets", "using a java slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code snippets", "locating bug core 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 a java snippets\") OR (\"vi hanh va snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using a java snippets ) OR ( vi hanh va snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using a java snippets") OR ("vi hanh va snippets"))) OR ("locating bug code snippets"))*.
