Perhaps you should try some spelling variations:
"python using sat snippets" » "python using data snippets", "python using a snippets", "python using raw snippets"
"tri cho code snippets" » "tri cho cong snippets", "tri cfd code snippets", "tri cho con snippets", "tri co code snippets", "tri nho code snippets", "tri chi code snippets"
"locating bug core snippets" » "locating bug code 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 cho code snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using sat snippets ) OR ( tri cho code snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using sat snippets") OR ("tri cho code snippets"))) OR ("locating bug core snippets"))*.
