Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"chi hap ban snippets" » "chi ha ban snippets", "thi phap ban snippets", "chi phan ban snippets", "chi lap ban snippets", "chi hap dan snippets", "chi nhat ban 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 (\"chi hap ban snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( chi hap ban snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("chi hap ban snippets"))) OR ("locating bug core snippets"))*.
