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 data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets"
"tri noi dan snippets" » "tri doi dan snippets", "tri moi dan snippets", "tri ngoai dan snippets", "tri hoi dan snippets", "tri noi da 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 data snippets\") OR (\"tri noi dan snippets\"))) OR (\"locating bug code slippers\"))~".
• Removing quotes may allow a broader search: (((( python using data snippets ) OR ( tri noi dan snippets ))) OR ( locating bug code slippers ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using data snippets") OR ("tri noi dan snippets"))) OR ("locating bug code slippers"))*.
