Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"lua cau dat snippets" » "luat cau dat snippets", "cua cau dat snippets", "quan cau dat snippets", "lua cai dat snippets", "lua cau hat snippets", "lua chap dat 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 (\"lua cau dat snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( lua cau dat snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("lua cau dat snippets"))) OR ("locating bug core snippets"))*.
