Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"j van code snippets" » "j van de snippets", "j van hoe snippets", "j van cong snippets", "_ van code snippets", "b van code snippets", "m van code snippets"
"locating bug core snippets" » "locating bug code snippets"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("j van code snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"j van code snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))".
• Removing quotes may allow a broader search: (((( j van code snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets )).
• Adding a wildcard symbol may retrieve word variants: (((("j van code snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
