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"
"thuat doi 3 snippets" » "thuat do 3 snippets", "thuat di 3 snippets", "thuat doc 3 snippets", "thuat doi _ snippets", "thuat moi 3 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 (\"thuat doi 3 snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java slippery ) OR ( thuat doi 3 snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java slippery") OR ("thuat doi 3 snippets"))) OR ("locating bug core snippets"))*.
