Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"thu can van snippets" » "thu canh van snippets", "thuc can van snippets", "thu ban van snippets", "thu cac van snippets", "thu can ban snippets", "thu tan van snippets", "thu can van 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 can van snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( thu can van snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("thu can van snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
