Perhaps you should try some spelling variations:
"using java java snippets" » "using data java snippets"
"doi hanh va slippers" » "doc hanh va slippers", "doi khang va slippers", "thi hanh va slippers", "doi hang va slippers", "doi hanh vi slippers", "doi hanh va slippery", "doi hanh va grippers"
"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: "((((\"using java java snippets\") OR (\"doi hanh va slippers\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java java snippets ) OR ( doi hanh va slippers ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java java snippets") OR ("doi hanh va slippers"))) OR ("locating bug code snippets"))*.
