Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"doi su ngan snippets" » "doi sau ngan snippets", "doi vu ngan snippets", "doi tu ngan snippets", "oi su ngan snippets", "don su ngan snippets", "voi su ngan snippets", "doi su ngan 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: "((((\"python using java snippets\") OR (\"doi su ngan snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( doi su ngan snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("doi su ngan snippets"))) OR ("locating bug code snippets"))*.
