Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"chi tao ban snippets" » "che tao ban snippets", "chi dao ban snippets", "cai tao ban snippets", "chi tao bac snippets", "chi cao bang snippets", "chi tao nhan 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 tao ban snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( chi tao ban snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("chi tao ban snippets"))) OR ("locating bug core snippets"))*.
