Perhaps you should try some spelling variations:
"xa dung lan grippers" » "xa dung luan grippers", "xa dung land grippers", "xa dung lam grippers", "xay dung lan grippers", "xa dong lan grippers", "va dung lan grippers", "xa dung 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: "((((\"xa dung lan grippers\") OR (\"python using a snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( xa dung lan grippers ) OR ( python using a snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("xa dung lan grippers") OR ("python using a snippets"))) OR ("locating bug code snippets"))*.
