Perhaps you should try some spelling variations:
"python using code snippets" » "python using cfd snippets", "python using one snippets"
"locating bug core snippets" » "locating bug code snippets"
"ly tu tuong snippets" » "ly thu tuong snippets", "ly du tuong snippets", "ly su tuong snippets", "ly tu truong snippets", "ly tu thuong snippets", "ly tu huong snippets"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("ly tu tuong snippets") OR ("python using code snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ly tu tuong snippets\") OR (\"python using code snippets\"))) OR (\"locating bug core snippets\"))*".
• Removing quotes may allow a broader search: (((( ly tu tuong snippets ) OR ( python using code snippets ))) OR ( locating bug core snippets ))*.
