Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"nhan do a snippets" » "nhan dot a snippets", "nhan mo a snippets", "nhan co a snippets", "nhan do va snippets", "nhan do ba snippets", "nhan do xa 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: "((((\"nhan do a snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( nhan do a snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("nhan do a snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
