Perhaps you should try some spelling variations:
"le trong code snippets" » "le trong cong snippets", "le trong co snippets", "le trong che snippets", "le trung code snippets", "ly trong code snippets", "le tang code snippets"
"using sat java snippets" » "using data java snippets", "using a java snippets", "using raw java snippets", "using sat va snippets"
"locating bug core snippets" » "locating bug 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 sat java snippets\") OR (\"le trong code snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( using sat java snippets ) OR ( le trong code snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using sat java snippets") OR ("le trong code snippets"))) OR ("locating bug core snippets"))*.
