Perhaps you should try some spelling variations:
"thi than lan snippets" » "thi phan lan snippets", "thi than man snippets", "thi thanh loan snippets", "thi thanh lan snippets", "thi thuan lan snippets", "thi thao lan snippets", "thi than lan 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: "((((\"python using a snippets\") OR (\"thi than lan snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using a snippets ) OR ( thi than lan snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using a snippets") OR ("thi than lan snippets"))) OR ("locating bug code snippets"))*.
