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