Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"dac san tin snippets" » "dac sac tin snippets", "cac san tin snippets", "dac nhan tin snippets", "dac san tinh snippets", "dac van tin snippets", "dac san ten snippets", "dac san tin 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: "((((\"dac san tin snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( dac san tin snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dac san tin snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
