Perhaps you should try some spelling variations:
"locatinhg bug code snippets" » "locating bug code snippets", "locatinhg bug core snippets"
"python using java snippets" » "python using data snippets"
"doi ba cau snippets" » "doi ban cau snippets", "doi bai cau snippets", "doi bo cau snippets", "doi bac cau 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 ba cau snippets\"))) OR (\"locatinhg bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( doi ba cau snippets ))) OR ( locatinhg bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("doi ba cau snippets"))) OR ("locatinhg bug code snippets"))*.
