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