Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"de doi c snippets" » "te doi c snippets", "ve doi c snippets", "ke doi c snippets", "de doi co snippets", "de doi ca snippets", "de doi _ 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 (\"de doi c snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( de doi c snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("de doi c snippets"))) OR ("locating bugs code snippets"))*.
