Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using data java snippets" » "using java java snippets", "using sat java snippets", "missing data java snippets"
"vi using low snippets" » "vi sinh low snippets", "_ using low snippets", "vi ung low 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 data java snippets\") OR (\"vi using low snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using data java snippets ) OR ( vi using low snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using data java snippets") OR ("vi using low snippets"))) OR ("locating bugs code snippets"))*.
