Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"van gian le snippets" » "van gian code snippets", "van giang le snippets", "dan gian le snippets", "van giao le snippets", "van gian ve snippets", "van gian e snippets"
"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 gian le snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( van gian le snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("van gian le snippets"))) OR ("locating bug core snippets"))*.
