Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets"
"xa dung dat slippery" » "xa dung va slippery", "xa dung tai slippery", "xay dung dat slippery", "xa dong dat slippery", "va dung dat slippery", "xa dung dat slippers"

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 dat slippery\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( xa dung dat slippery ) OR ( python using data snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("xa dung dat slippery") OR ("python using data snippets"))) OR ("locating bug core snippets"))*.
