Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"so tinh li snippets" » "o tinh li snippets", "so tin li snippets", "hoi tinh li snippets", "so tinh lai snippets", "so sinh li snippets", "so dinh li snippets", "so tinh li 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: "((((\"so tinh li snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( so tinh li snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("so tinh li snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
