Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"hat con cua snippets" » "hai con cua snippets", "hat mon cua snippets", "vat con cua snippets", "hat cong cua snippets", "hat co cua snippets", "hat dong cua 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: "((((\"hat con cua snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( hat con cua snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("hat con cua snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
