Perhaps you should try some spelling variations:
"python using code snippets" » "python using cfd snippets", "python using one snippets"
"son tang phi snippets" » "son tung phi snippets", "son thanh phi snippets", "nen tang phi snippets", "son tang thi snippets", "son lang phi snippets", "son tang phu snippets"
"locating bug core snippets" » "locating bug code snippets"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("son tang phi snippets") OR ("python using code snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"son tang phi snippets\") OR (\"python using code snippets\"))) OR (\"locating bug core snippets\"))".
• Removing quotes may allow a broader search: (((( son tang phi snippets ) OR ( python using code snippets ))) OR ( locating bug core snippets )).
• Adding a wildcard symbol may retrieve word variants: (((("son tang phi snippets") OR ("python using code snippets"))) OR ("locating bug core snippets"))*.
