Perhaps you should try some spelling variations:
"van ba tham slices" » "van ba ham slices", "van va tham slices", "van van tham slices", "van ban tham slices", "van bao tham slices", "van bac tham slices"
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets", "python using data 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: "((((\"python using data snippets\") OR (\"van ba tham slices\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using data snippets ) OR ( van ba tham slices ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using data snippets") OR ("van ba tham slices"))) OR ("locating bug code snippets"))*.
