Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"using raw java snippets" » "using real java snippets", "using a java snippets", "using low java snippets", "using raw java slippers"
"vi qua van snippets" » "vi quan van snippets", "vi qua ban snippets", "vi qua san snippets", "va qua van snippets", "vi lua van snippets", "vi qua van slippers"

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: "((((\"vi qua van snippets\") OR (\"using raw java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( vi qua van snippets ) OR ( using raw java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("vi qua van snippets") OR ("using raw java snippets"))) OR ("locating bugs code snippets"))*.
