Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets", "using java core snippets"
"lang trong ca snippets" » "dung trong ca snippets", "cong trong ca snippets", "dong trong ca snippets", "lang trong cac snippets", "lang trong van snippets", "lang trong nha snippets"
"locating bug code snippets" » "locating bug core 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: "((((\"using java code snippets\") OR (\"lang trong ca snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( lang trong ca snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("lang trong ca snippets"))) OR ("locating bug code snippets"))*.
