Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"thu hai mat snippets" » "thu ha mat snippets", "thu nhap mat snippets", "thu hang mat snippets", "thu ham mat snippets", "thu gai mat snippets", "thu cham mat snippets", "thu hai mat 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: "((((\"thu hai mat snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( thu hai mat snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("thu hai mat snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
