Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"hoc can tri snippets" » "hoc dan tri snippets", "hoc cao tri snippets", "hoc cac tri snippets", "hoc can thi snippets", "hoc van tri snippets", "hoc cai tri 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: "((((\"hoc can tri snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( hoc can tri snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("hoc can tri snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
