Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"tu cong ba snippets" » "thu cong ba snippets", "te cong ba snippets", "tai cong ba snippets", "tu cong bao snippets", "tu cong ha snippets", "tu cong va 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 (\"tu cong ba snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( tu cong ba snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("tu cong ba snippets"))) OR ("locating bug core snippets"))*.
