Perhaps you should try some spelling variations:
"python using code snippets" » "python using cfd snippets", "python using one snippets"
"tri mot dan snippets" » "tri mat dan snippets", "tri moi dan snippets", "tri mot lan snippets"
"locating bug code slippers" » "locating bung code slippers", "locating bugs code slippers"

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 code snippets\") OR (\"tri mot dan snippets\"))) OR (\"locating bug code slippers\"))~".
• Removing quotes may allow a broader search: (((( python using code snippets ) OR ( tri mot dan snippets ))) OR ( locating bug code slippers ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using code snippets") OR ("tri mot dan snippets"))) OR ("locating bug code slippers"))*.
