Perhaps you should try some spelling variations:
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets", "python using data slippers"
"cua va lanh snippets" » "cua va lang snippets", "cua va danh snippets", "cua va hanh snippets", "cua vat lanh snippets", "chua va lanh snippets", "cua van lanh snippets", "cua va lanh 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: "((((\"cua va lanh snippets\") OR (\"python using data snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( cua va lanh snippets ) OR ( python using data snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("cua va lanh snippets") OR ("python using data snippets"))) OR ("locating bug code snippets"))*.
