Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using cfd snippets" » "python using code snippets", "python using 3d snippets", "python using c snippets"
"ly ly trong snippets" » "ly le trong snippets", "ly cay trong snippets", "ly ro trong snippets", "ly ky trong snippets", "ly y 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 ly trong snippets\") OR (\"python using cfd snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( ly ly trong snippets ) OR ( python using cfd snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("ly ly trong snippets") OR ("python using cfd snippets"))) OR ("locating bug core snippets"))*.
