Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"khoa dan ra snippets" » "khoa dang ra snippets", "hoa dan ra snippets", "khoa can ra snippets", "khoa dan tra snippets", "khoa dan ca snippets", "khoa dan va 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: "((((\"khoa dan ra snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( khoa dan ra snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("khoa dan ra snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
