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"
"tri hoc dap snippets" » "triet hoc dap snippets", "tri thuc dap snippets", "thai hoc dap snippets", "tri hoc dan snippets", "tri hoc dai snippets", "tri hoc tap 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 (\"tri hoc dap snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using sat snippets ) OR ( tri hoc dap snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using sat snippets") OR ("tri hoc dap snippets"))) OR ("locating bug core snippets"))*.
