Hi,

i have logs in the format  
[2017-01-13 21:21:03,956][WARN][index.search.slowlog.query] [Yaswanth] [bank][0] took[28.9ms], took\_millis[28], types[], stats[], search\_type[QUERY\_THEN\_FETCH], total\_shards[5], source[], extra\_source[],

when i send it to .csv file it is showing like this ,because the default separator is ","

[2017-01-13 21:21:03 --column 1  
956][WARN][index.search.slowlog.query] [Yaswanth] [bank][0] took[28.9ms] --column 2  
took\_millis[28] --column 3  
types[] --column4  
stats[] --column 5  
search\_type[QUERY\_THEN\_FETCH] --column 6  
total\_shards[5] --column 7  
source[] --column 8  
extra\_source[] --column 9

But what i want is the content that is in "[]" .  
2017-01-13 21:21:03,956 column1  
WARN column 2  
index.search.slowlog.query column 3  
and so on.. column ......

Even i tried giving

csr {  
separator =\> "[]"  
}  
But nothing worked..

Can anyone help me on this?  
Thanks
