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