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