Perhaps you should try some spelling variations:
"moi co chat snippets" » "moi co code snippets", "moi cao chat snippets", "moi co cham snippets", "moi co hat snippets", "mai co chat snippets"
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data 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 (\"moi co chat snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( moi co chat snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("moi co chat snippets"))) OR ("locating bug core snippets"))*.
