Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"do danh tao snippets" » "do doanh tai snippets", "do danh giao snippets", "do dao tao snippets", "do dinh tao snippets", "do sanh tao snippets", "dia danh tao snippets", "do danh tao 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: "((((\"do danh tao snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( do danh tao snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("do danh tao snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
