Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"cat mat can snippets" » "cat map can snippets", "cat may can snippets", "cham mat can snippets", "cat bat can snippets", "cat mat dan snippets", "cat mao can snippets"
"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 (\"cat mat can snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( cat mat can snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("cat mat can snippets"))) OR ("locating bug code snippets"))*.
