Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"quan cuu va snippets" » "quan cua va snippets", "quan cau va snippets", "quan chu va snippets", "quan cuu van snippets", "quan cuu ve 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: "((((\"quan cuu va snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( quan cuu va snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("quan cuu va snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
