Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"doi cua xac snippets" » "hoi cua xac snippets", "dai cua xac snippets", "dong cua xac snippets", "doi cua cac snippets", "doi cua bac snippets", "doi cuu xac snippets", "doi cua xac 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: "((((\"doi cua xac snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( doi cua xac snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("doi cua xac snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
