Extract URL field in datamodel

[user2020dy]

Hello, guys

I`m trying to extract URL field from my log in Data Model (it is not extracted from _raw log and is not seen via index). I have found some variants in similar topics and added a new field (with regular expression) to Data Model. It does not cover 100% of my events, but it works.

However, I still don`t see this field when run the command

| from datamodel Network_Traffic

2 questions:

1) Can anyone answer me why the field is still not seen when whiting the search

| from datamodel Network)Traffic

Because the "Preview" tab shows the results and URLs are extracted 

2) Maybe you know how I can extract the field URL directly from _raw event, because I`m confused with all answers which I saw about this topic before.

Tranks in advance

can you check your regex used to extract url once ?

apply same regex using rex command to see if that is working or not.

yes, the search works fine, but if I add this rex to extract a field "URL" in datamodel, the new  field doesn`t appear
