Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"mat dan anh snippets" » "hat dan anh snippets", "luat dan anh snippets", "mat bang anh snippets", "mat dan canh snippets", "mat dan hanh snippets", "mat van anh snippets", "mat dan anh slippers"
"locating bug code snippets" » "locating bug code slippers", "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: "((((\"mat dan anh snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( mat dan anh snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("mat dan anh snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
