Is there a way to display the contents which match the text filters, just like EmEditor or Microsoft Excel data filter?

no, but something is possible in plugin API, so try to make the plugin:

- plugin can find all lines for filter-string and put them to a new empty document
- or, plugin can find all lines not ok for filter-string and make folding ranges for them, and fold all those ranges

Thank you for these information!

Could someone help to create such a plugin?

You can do this to some extent without a new plugin if you have the plugin Cuda_ext installed.
Use Cudatext "find" and under the three dots choose select all.
This will put a cursor on every line that has a found item.
Use the Cuda_ext command, under Misc, Fold lines without carets.

"Plugins / Cuda-Ext / Misc / Fold lines without carets" menu item. interesting idea...
