Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"thi nam dau snippets" » "thai nam dau snippets", "thi tam dau snippets", "chi nam dau snippets", "thi nam dan snippets", "thi nam da snippets", "thi lam dau 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: "((((\"python using java snippets\") OR (\"thi nam dau snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( thi nam dau snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("thi nam dau snippets"))) OR ("locating bug core snippets"))*.
