Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"vi va trinh snippets" » "vi van trinh snippets", "vi va tinh snippets", "vi lap trinh snippets", "vai va trinh snippets", "vu va trinh snippets", "vi va trinh 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: "((((\"vi va trinh snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( vi va trinh snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("vi va trinh snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
