Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"nhan dot 4 snippets" » "nhan dat 4 snippets", "nhay dot 4 snippets", "nhan dong 4 snippets", "nhan do 4 snippets", "nhan doc 4 snippets", "nhan dot a 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: "((((\"nhan dot 4 snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( nhan dot 4 snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("nhan dot 4 snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
