Perhaps you should try some spelling variations:
"python using raw snippets" » "python using real snippets", "python using a snippets", "python using low snippets", "python using raw slippers"
"cua dau lanh snippets" » "cua cau lanh snippets", "cua dat lanh snippets", "cua dau tranh snippets", "chua dau lanh snippets", "cua dan lanh snippets", "cua dai lanh snippets", "cua dau lanh slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code snippets", "locating bug core 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: "((((\"cua dau lanh snippets\") OR (\"python using raw snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( cua dau lanh snippets ) OR ( python using raw snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("cua dau lanh snippets") OR ("python using raw snippets"))) OR ("locating bug code snippets"))*.
