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