Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"doi hoc bai snippets" » "doi hoac bai snippets", "dai hoc bai snippets", "hoi hoc bai snippets", "doi hoc dai snippets", "doi hoc giai 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 (\"doi hoc bai snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( doi hoc bai snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("doi hoc bai snippets"))) OR ("locating bug core snippets"))*.
