Perhaps you should try some spelling variations:
"python using code snippets" » "python using cfd snippets", "python using one snippets"
"ly van tang snippets" » "ly van thang snippets", "ly van trang snippets", "ly van nang snippets", "le van tang snippets", "ly va tang snippets", "ly von tang snippets"
"locating bug core snippets" » "locating bug code 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: "((((\"ly van tang snippets\") OR (\"python using code snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( ly van tang snippets ) OR ( python using code snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("ly van tang snippets") OR ("python using code snippets"))) OR ("locating bug core snippets"))*.
