Perhaps you should try some spelling variations:
"missing java java snippets" » "missing data java snippets", "using java java snippets"
"vi ung chet snippets" » "vi dung chet snippets", "vi dung chat snippets", "vi cung chem snippets", "va ung chet snippets", "vi luong chet snippets", "vi trung chet snippets"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code snippets", "locating bug core 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: "((((\"missing java java snippets\") OR (\"vi ung chet snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( missing java java snippets ) OR ( vi ung chet snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("missing java java snippets") OR ("vi ung chet snippets"))) OR ("locating bug code snippets"))*.
