Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"hoc anh lua snippets" » "hoc nganh lua snippets", "hoc nhanh lua snippets", "hoc sinh lua snippets", "hoc anh cua snippets", "hoc hanh luat snippets", "hoc anh tuan 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 (\"hoc anh lua snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( hoc anh lua snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("hoc anh lua snippets"))) OR ("locating bug core snippets"))*.
