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