Perhaps you should try some spelling variations:
"dao do cach snippets" » "dao do code snippets", "dao doi cach snippets", "dao do cac snippets", "dao co cach snippets", "dao o cach snippets", "dao ho cach snippets", "dao dong cach snippets"
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("python using java snippets") OR ("dao do cach snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"python using java snippets\") OR (\"dao do cach snippets\"))) OR (\"locating bug core snippets\"))*".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( dao do cach snippets ))) OR ( locating bug core snippets ))*.
