Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using raw snippets" » "python using real snippets", "python using a snippets", "python using low snippets"
"do thu phan snippets" » "do thu nhan snippets", "do thuat phan snippets", "do than phan snippets", "do thuc phan snippets", "doi thu phan snippets", "do thuy phan 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 raw snippets\") OR (\"do thu phan snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using raw snippets ) OR ( do thu phan snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using raw snippets") OR ("do thu phan snippets"))) OR ("locating bug core snippets"))*.
