Perhaps you should try some spelling variations:
"locating bug code slippers" » "locating bug code snippets", "locating bung code slippers", "locating bugs code slippers"
"python using java snippets" » "python using data snippets"
"quan ha dua snippets" » "quan he dua snippets", "quan hat dua snippets", "quan ca dua snippets", "quan ho dua 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: "((((\"quan ha dua snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code slippers\"))~".
• Removing quotes may allow a broader search: (((( quan ha dua snippets ) OR ( python using java snippets ))) OR ( locating bug code slippers ))~.
• Adding a wildcard symbol may retrieve word variants: (((("quan ha dua snippets") OR ("python using java snippets"))) OR ("locating bug code slippers"))*.
