Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"van lieu ma snippets" » "vat lieu ma snippets", "van hieu ma snippets", "van lien ma snippets", "van lieu va snippets", "van lieu tai snippets", "van lieu bai snippets", "van lieu ma slippers"
"locating bug code snippets" » "locating bug code slippers", "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: "((((\"van lieu ma snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( van lieu ma snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("van lieu ma snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
