Filters in Kibana

Need to find logs about errors in Kibana. I can add a filter by content of a message but it's a temporary solution. How can I make this filter constant (not just pin)? What is the best way to do it? May be there are other solutions, not about filters in Kibana? Thank you for help!

You can do this also from the Discover tab:

You need to use a logstash filter , this enables you split your entire log message into elements (see picture 2), that way you can easily read your messages and it lets you focus on the important attributes.
