Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"da su doi snippets" » "da sua doi snippets", "da su dai snippets", "da tu doi snippets", "dan su doi snippets", "dat su doi snippets", "va su doi 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 (\"da su doi snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( da su doi snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("da su doi snippets"))) OR ("locating bug code snippets"))*.
