Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"len dan dat snippets" » "le dan dat snippets", "lan dan dat snippets", "nen dan dat snippets", "len dung dat snippets", "len dong dat snippets", "len dinh dat snippets", "len dan dat 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: "((((\"python using java snippets\") OR (\"len dan dat snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( len dan dat snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("len dan dat snippets"))) OR ("locating bug code snippets"))*.
