Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"doi anh du snippets" » "doi hanh du snippets", "doi canh du snippets", "doi sanh du snippets", "doi anh duc snippets", "doi danh du snippets", "doi anh d 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 (\"doi anh du snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( doi anh du snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("doi anh du snippets"))) OR ("locating bugs code snippets"))*.
