Perhaps you should try some spelling variations:
"phi va chet snippets" » "phi va code snippets", "phi va chiet snippets", "phi va che snippets", "phi va chat snippets", "phai va chet snippets"
"locating bug core snippets" » "locating bug code snippets"
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data 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: "((((\"phi va chet snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( phi va chet snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("phi va chet snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))*.
