Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using sat snippets" » "python using data snippets", "python using a snippets", "python using raw snippets"
"hoi vu thi snippets" » "hoi va thi snippets", "hoi tu thi snippets", "hai vu thi snippets", "hoi su thi 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 sat snippets\") OR (\"hoi vu thi snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using sat snippets ) OR ( hoi vu thi snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using sat snippets") OR ("hoi vu thi snippets"))) OR ("locating bug core snippets"))*.
