Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"doi can van snippets" » "doi canh van snippets", "doi ban van snippets", "voi can van snippets", "doi cac van snippets", "doi can ban snippets", "doi tan van snippets", "doi can van 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: "((((\"doi can van snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( doi can van snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("doi can van snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
