Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets"
"cu nhan vao snippets" » "cu nhan tao snippets", "cu nhan va snippets", "cu nhan vat snippets", "ca nhan vao 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 data snippets\") OR (\"cu nhan vao snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using data snippets ) OR ( cu nhan vao snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using data snippets") OR ("cu nhan vao snippets"))) OR ("locating bug core snippets"))*.
