After a long study, I found a stable working method, but I will give an information so that other people can benefit from it. 
The guide I mentioned above is a very effective method, but it does have some problems and this is due to the plugins.
The Recycler List View plugin mentioned in the guide is a very useful plugin. Version 1.0.1 is used in the guide.
Currently, there is version 1.0 on the plugin page and it is impossible to prepare a platform like the one in this guide with this version because version 1.0 does not have the blocks used in the guide.As an extra, there is the latest version, 1.0.3. I installed this version and transferred it to my project and set up the platform. But I noticed that the search section is not working stably.
Later, I tried the same CSV table with the AIA file in the guide and it was working stably.I noticed that the plugin version 1.0.1 works more stable (by the way, the file size is more than 8000 lines)
and I immediately looked at the plugin content
Below are the code lines of two different Recycler List View plugins
Version 1.0.3 is a newer and more detailed version, but the application becomes unresponsive when searching in a csv table with 8000 rows.
The version 1.0.1 used in the guide I mentioned works stably.
Both of them load the list but 1.0.1 works for searching and my system is working smoothly now.
I’m tagging the plugin owner and those who are interested in the topic. Happy coding. Thank you for your support. @zainulhassan , @RaYzZz , @Ibrahim_Jamar , @dora_paz
