Perhaps you should try some spelling variations:
"trinh anh ca snippets" » "trinh hanh ca snippets", "trinh thanh ca snippets", "trinh kinh ca snippets", "trinh danh ca snippets", "trinh anh cam snippets", "trinh anh cua snippets"
"trong cac code snippets" » "trong cac cong snippets", "trong cac co snippets", "trong cac che snippets"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code 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: "((((\"trinh anh ca snippets\") OR (\"trong cac code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( trinh anh ca snippets ) OR ( trong cac code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("trinh anh ca snippets") OR ("trong cac code snippets"))) OR ("locating bug code snippets"))*.
