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