Hello,

I'm building an app with Dash, i created a checklist, that returns a list of terms. I use that list to filter on my fields. But when there is no filter i don't know how to inform my query to not filter on anything.

here is my query i'm using python:

all\_dep  
all\_domaineA  
all\_typeA

Are the three list i obtain from my dash app. They can be either filled [value,value] or empty []. I'm then wondering if there is any value i could replace my object by, to not filter any value.

```
> res = es.search(
> index="cluster_all", 
> size=10000, 
> body= { "_source": ['geoloc',"societe"],
> "size" : 10000,
> "query": {
> "bool": {
> "must": {
> "match_all": {}
> },
> "filter" : [
> { "terms" : { "num_dep" : all_dep}},
> { "terms" : { "typeA" : all_typeA }},
> { "terms" : { "domaineA" : all_domaineA }}
> ]
> }
> }
> }
> )
```
