Perhaps you should try some spelling variations:
"hoi lang vat snippets" » "hoa lang vat snippets", "hoi dan vat snippets", "hoi lang van snippets", "hoi dang vat snippets", "hoi bang vat snippets", "hoi lang vat slippers"
"using low java snippets" » "using low java slippers"
"locating bug code snippets" » "locating bug code slippers", "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: "((((\"hoi lang vat snippets\") OR (\"using low java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( hoi lang vat snippets ) OR ( using low java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("hoi lang vat snippets") OR ("using low java snippets"))) OR ("locating bug code snippets"))*.
