Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using sat snippets" » "python using data snippets", "python using a snippets", "python using raw snippets"
"le manh tu snippets" » "le minh tu snippets", "le anh tu snippets", "le thanh tu snippets", "le danh tu snippets", "le hanh tu 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: "((((\"le manh tu snippets\") OR (\"python using sat snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( le manh tu snippets ) OR ( python using sat snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("le manh tu snippets") OR ("python using sat snippets"))) OR ("locating bug core snippets"))*.
