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