Perhaps you should try some spelling variations:
"locating bug code slippers" » "locating bug code snippets", "locating bung code slippers", "locating bugs code slippers"
"python using raw snippets" » "python using real snippets", "python using a snippets", "python using low snippets"
"cac dan tinh snippets" » "cac doan tinh snippets", "cac dang tinh snippets", "cac dan trinh 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 (\"cac dan tinh snippets\"))) OR (\"locating bug code slippers\"))~".
• Removing quotes may allow a broader search: (((( python using raw snippets ) OR ( cac dan tinh snippets ))) OR ( locating bug code slippers ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using raw snippets") OR ("cac dan tinh snippets"))) OR ("locating bug code slippers"))*.
