What is the maximum that we can set for index.query.bool.max\_clause\_count(old versions) and indices.query.bool.max\_clause\_count (\>5.1)?

Hi Abbas,

I believe it's 1024 in versions \>5.1

Though I'd like to help by finding out how you're hitting this limit.  
If you only need to filter docs with a bool query, then perhaps you can do a bool filter instead of a bool must.  
~~This would avoid this max setting as this setting is specific to scoring so shouldn't apply to filtering.~~  
It depends if you need to score each document though.

Most cases I've seen where this has been hit have been filtering scenarios rather than scoring ones.

**CORRECTION** : Using a bool filter instead of a bool must will still hit the same max clause limit if you use more than the maximum number of clauses in your bool filter.
