I'm using elastic stack 7.3.2. I need to use working logstash config on new version. This one construction work perfect on version 6.5.0, but don't work on 7.3.2  
filter {  
csv {  
columns =\> ["column1","column2","column3","column4"]  
separator =\> ", "  
quote\_char=\> "'"  
source =\> "log"  
}  
if [column2] == "" {  
drop{}  
}  
if ![column3] {  
drop{}  
}  
}  
But in my new index still appear documents with empty column3 and column2.  
Can someone correct me?

Hi. Probably i think you could reach this by:

> **Summary**

> ```
> filter {
> csv {
> columns => ["column1","column2","column3","column4"]
> separator => ", "
> quote_char=> "'"
> source => "log"
> }
> if [column2] ~= "" and [column3] {
> mutate {
> add_tag => ["true"]
> }
> }
> }
> }
> 
> output {
> if [tags] == "true" {
> elasticsearch {
> ...

> }
