Perhaps you should try some spelling variations:
"python using sat snippets" » "python using data snippets", "python using a snippets", "python using raw snippets", "python using sat slippers"
"tri van hai snippets" » "thi van hai snippets", "tri va hai snippets", "trinh van hai snippets", "tri van ha snippets", "tri van chat snippets", "tri van hanh snippets", "tri van hai slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code snippets", "locating bug core 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 van hai snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using sat snippets ) OR ( tri van hai snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using sat snippets") OR ("tri van hai snippets"))) OR ("locating bug code snippets"))*.
