Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"thi ngan da slippers" » "tai ngan da slippers", "thu ngan da slippers", "thi nga da slippers", "thi ngan danh slippers", "thi nganh dao slippers", "thi nganh dau slippers", "thi ngan da slippery", "thi ngan da grippers"
"locating bug code snippets" » "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 (\"thi ngan da slippers\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( thi ngan da slippers ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("thi ngan da slippers"))) OR ("locating bug code snippets"))*.
