Perhaps you should try some spelling variations:
"tri hoang dang snippets" » "tri hoang dung snippets", "tri hoang lang snippets", "tri hoang duong snippets", "tri hoan dang snippets", "thi hoang dang snippets", "tri hang dang snippets", "tri hoang dang 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 (\"tri hoang dang snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using a snippets ) OR ( tri hoang dang snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using a snippets") OR ("tri hoang dang snippets"))) OR ("locating bug code snippets"))*.
