Perhaps you should try some spelling variations:
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets"
"de from pre snippets" » "de from core snippets", "de from bee snippets", "de from e snippets", "dye from pre snippets", "me from pre 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: "((((\"de from pre snippets\") OR (\"python using data snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( de from pre snippets ) OR ( python using data snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("de from pre snippets") OR ("python using data snippets"))) OR ("locating bug code snippets"))*.
