Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"doi so than snippets" » "doi so phan snippets", "doi so thao snippets", "doi so tan snippets", "dai so than snippets", "doi bo than snippets", "doi co than snippets", "doi so than 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 so than snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( doi so than snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("doi so than snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
