Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"lap doc duc snippets" » "lap doi duc snippets", "lap dong duc snippets", "phap doc duc snippets", "lap do duc snippets", "lap hoc duc snippets", "lap duoc duoc snippets", "lap doc duc 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: "((((\"python using java snippets\") OR (\"lap doc duc snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( lap doc duc snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("lap doc duc snippets"))) OR ("locating bug code snippets"))*.
