Trying to learn GROK by using the GROK debugger tool in Kibana.

Data is stuctured like this:

param1=value1 param2="value 2" param4=param4  
param1=value1 param2="value 2" param3=param3 param4=param4

Questions are:

1. Will I be able to write a filter/GROK that takes care of a dynamic structure (sometimes paramX is missing)?

2. Do I need to define the structure? Can't I just make [foreach paramX, store the key paramX with a value of valueX]?

The only thing that's complicating parsing is that sometimes valueX contains one or more spaces, but then its surrounded by "

Thank you very much for your support!

Why not use a [kv](https://www.elastic.co/guide/en/logstash/current/plugins-filters-kv.html) filter?
