Perhaps you should try some spelling variations:
"ty con truong snippets" » "ty chon truong snippets", "ty cong truong snippets", "ty con trung snippets", "ty co truong snippets", "ta con truong snippets", "tay cong truong snippets", "ty con truong slippers"
"python using a snippets" » "python using a 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: "((((\"ty con truong snippets\") OR (\"python using a snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( ty con truong snippets ) OR ( python using a snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("ty con truong snippets") OR ("python using a snippets"))) OR ("locating bug code snippets"))*.
