Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"tri nha dan slippers" » "tri nhan dan slippers", "trai nha dan slippers", "tri nho dan slippers", "tri nhac dan slippers", "tri nha van slippers", "tri nha dan slippery", "tri nha dan 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 (\"tri nha dan slippers\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( tri nha dan slippers ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("tri nha dan slippers"))) OR ("locating bug code snippets"))*.
