Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java slippery" » "python using data slippery", "python using java slippers"
"tham du 3 snippets" » "thap du 3 snippets", "tham do 3 snippets", "pham duc 3 snippets", "tham du _ snippets", "tham du f 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 java slippery\") OR (\"tham du 3 snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java slippery ) OR ( tham du 3 snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java slippery") OR ("tham du 3 snippets"))) OR ("locating bug core snippets"))*.
