Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"dan cho mo snippets" » "danh cho mo snippets", "san cho mo snippets", "dac cho mo snippets", "dan cho moi snippets", "dan cho mot snippets", "dan cho ro snippets"
"locating bug code snippets" » "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: "((((\"dan cho mo snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( dan cho mo snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dan cho mo snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
