Perhaps you should try some spelling variations:
"python using raw snippets" » "python using real snippets", "python using a snippets", "python using low snippets"
"locating bug core snippets" » "locating bug code snippets"
"hanh ca code snippets" » "hanh cac code snippets", "hanh cat code snippets", "hanh cua code snippets", "hanh cfd code snippets"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("hanh ca code snippets") OR ("python using raw snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"hanh ca code snippets\") OR (\"python using raw snippets\"))) OR (\"locating bug core snippets\"))".
• Removing quotes may allow a broader search: (((( hanh ca code snippets ) OR ( python using raw snippets ))) OR ( locating bug core snippets )).
• Adding a wildcard symbol may retrieve word variants: (((("hanh ca code snippets") OR ("python using raw snippets"))) OR ("locating bug core snippets"))*.
