Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"toan phan h snippets" » "thanh phan h snippets", "toan ban h snippets", "hoa phan h snippets", "toan phan _ snippets", "toan phan thi snippets", "toan phan huy 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: "((((\"toan phan h snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( toan phan h snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("toan phan h snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
