Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"bach dan li snippets" » "bach dang li snippets", "bac dan li snippets", "bach van li snippets", "bach ban li snippets", "bach han li snippets", "bach pan li snippets", "bach dan li slippers"
"locating bug code snippets" » "locating bug code slippers", "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: "((((\"bach dan li snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( bach dan li snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("bach dan li snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
