Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using low snippets" » "python using code snippets"
"ly tao trong snippets" » "ly cay trong snippets", "ly ro trong snippets", "ly tai trong snippets", "ly dao trong snippets", "ly tam trong 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: "((((\"ly tao trong snippets\") OR (\"python using low snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( ly tao trong snippets ) OR ( python using low snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("ly tao trong snippets") OR ("python using low snippets"))) OR ("locating bug core snippets"))*.
