Re: Facet on multicore search when one field exists only in one of cores

[Claudio R]

 Hi Shawn,Thank you very much for your quick answer.The use of dynamic field 
"ignored" works, but it does not seem to be the correct way to solve the 
problem.We will try to equalize the cores.

Distributed queries must have compatible schemas in all the shards 
referenced.  If all fields referenced in the query are not covered by 
every one of those schemas, you're going to get an error.  This is just 
basic error-checking.

The only fix would be to correct the schemas.  You could add the missing 
field, or if you want all invalid fields ignored, simply set up a 
dynamicField named "*" that connects to a type that's ignored.  This 
should work:

    
    

I haven't actually tried this so I can't be SURE it will work, but I 
think it would.

A note for devs:  In the 8.1.0 _default configset, the "ignored" type 
does not have docValues="false" ... and I think docValues defaults to 
true on the StrField class.  I think that MIGHT be a problem.  Worth an 
issue?

Thanks,
Shawn
  

Facet on multicore search when one field exists only in one of cores

[Claudio R]

Hi,
I am using Solr 6.6.0 in mode standalone with 2 cores.
The first core has the schema:

id
fieldA
fieldB

The second core has the schema:

id
fieldA
fieldC

When I try this request to get facet of fields: fieldA, fieldB and fieldC on 
multicore search, I get error:

http://localhost:8983/solr/core1/select?q=*:*=localhost:8983/solr/core1,localhost:8983/solr/core2=*,[shard]=true=fieldA=fieldB=fieldC

Error from server at http://localhost:8983/solr/core2: 
undefined field: "fieldB"
400            

Is there any config / parameter in Solr to avoid this throw exception on facet 
of multicore when one field not exists in a core?

If I have this documents on cores:

core1:
id: "10"
fieldA: "productA"
fieldB: "value1"

core2:
id: "23"
fieldA: "productA"
fieldC: "value2"

I wish get a response like this:

Facet
fieldA
  productA (2)
fieldB
  value1 (1)
fieldC
  value2 (1)
