Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"do sy model snippets" » "do xy model snippets", "do sir model snippets", "do a model snippets", "do ky model snippets", "do my model snippets", "ho sy model snippets"
"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: "((((\"do sy model snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( do sy model snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("do sy model snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
