Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"python using data slippery" » "python using java slippery", "python using sat slippery", "python missing data slippery", "python using data slippers"
"tham doi _ snippets" » "thay doi _ snippets", "pham doi _ snippets", "thai doi _ 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: "((((\"python using data slippery\") OR (\"tham doi _ snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using data slippery ) OR ( tham doi _ snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using data slippery") OR ("tham doi _ snippets"))) OR ("locating bugs code snippets"))*.
