Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"do hai doc snippets" » "do bai doc snippets", "do hai huoc snippets", "do than doc snippets", "do thai doc snippets", "doc hai doc snippets", "do dai doc 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: "((((\"do hai doc snippets\") OR (\"python using java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( do hai doc snippets ) OR ( python using java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("do hai doc snippets") OR ("python using java snippets"))) OR ("locating bugs code snippets"))*.
