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