How to reduce quota size?

[jip31]

Hello

I use a very basic search on a short period like below but  I am a little surprised by the quota size used by this search (350 MO for 148000 events between 7h and 13h) 

index=tutu sourcetype="toto" type=x earliest=@d+7h latest=@d+19h 
| fields sam 
| eval sam=lower(s) 
| stats dc(s)

 So I try to find some tracks for reducing the quota size

Is anybody have an idea please?
