Well, I don't know the actual reason why the behavior is different
between Cloud and Embedded client: maybe things are different because in
the Embedded Solr HTTP is not involved at all, but I'm just shooting in
the dark.
I'm not aware about POST capabilities you mentioned, sorry

Yes, I realized that changing the method to GET solves the issue but it is
intentionally set to POST as in a real case scenario we had the issue of
users creating too long queries which where facing the REST length limits.
I think a possible solution would be to send the Solr params as a json in
the request body, but I am not sure if SolrJ supports this.

in front of me.
POST requests put the query in the request body, and the
EmbeddedSolrServer expects to find a valid JSON. Did you try to remove
the Method param?

Hi Andrea,
Thanks for your help, something which is relevant and I forgot to mention
before is that the requests are always a POST method.
As mentioned before, it is not a single query which fails but all of the
requests done to the search handler.
final SolrQuery q = new SolrQuery("!( _id_:"+ doc.getId()+")AND(_root_:"+
doc.getId()+")");
final QueryResponse query = solrClient.query(q, SolrRequest.METHOD.POST);
Regarding the embedded server instantiation:
.
.
.
final CoreContainer container = CoreContainer.createAndLoad(tmpSolrHome,
tmpSolrConfig);
return new SolrClientWrapper(container, CORE_NAME, tmpSolrHome);
.
.
.
private class SolrClientWrapper extends EmbeddedSolrServer {
private final Path temporaryFolder;
public SolrClientWrapper(CoreContainer coreContainer, String
coreName, Path temporaryFolder) {
super(coreContainer, coreName);
this.temporaryFolder = temporaryFolder;
}
.
.
.
The whole embedded server instantiation can be seen here

.

Hi Alfonso,
could you please paste an extract of the client code? Specifically those
few lines where you create the SolrQuery with params.
The line you mentioned is dealing with ContentStream which as far as I
remember wraps the request body, and not the request params. So as
request body Solr expects a valid JSON payload, but in your case, if I
got you, you're sending plain query parameters (through SolrJ).
Best,

Hi,
I am implementing a migration of Vind
<https://github.com/RBMHTechnology/vind> library from solr 5 to 7.4.0
and I
am facing an error which I have no idea how to solve...
The library provides a wrapper (and some extra stuff) to develop search
tools over Solr and uses SolrJ to access it, more info about it can be
seen
in the public repo, but basically all requests are done to solr
through a
client provided by solrj.
Actually, the migration is done and the tests running against a cloud
instance are working perfectly fine. The issue arises when testing
against
an embedded server (which is the default case as you may not have a
local
solr instance running), in which case every request fails throwing the
following exception:
*org.apache.solr.common.SolrException: Bad contentType for search
handler
:application/javabin request={q=!(+_id_:P3)AND(_root_:P3)}*
* at
org.apache.solr.request.json.RequestUtil.processParams(RequestUtil.java:73)*
* at
org.apache.solr.util.SolrPluginUtils.setDefaults(SolrPluginUtils.java:167)*

* at
org.apache.solr.client.solrj.SolrClient.query(SolrClient.java:974)*
* at
org.apache.solr.client.solrj.SolrClient.query(SolrClient.java:990)*
After some debugging I have seen that the embedded solr server uses
*org.apache.solr.request.json.RequestUtil* to process the parameters
which
invariable expects a '*application/json' *contentType but SolrJ
prodcues
as
*'application/javabin'.*
Any ideas on how to fix this issue?
The library has in the pom defined the following solr depedencies :
*.*
*.*
*.*
*<solr.version>7.4.0</solr.version>*
*.*
*.*
*.*
*<dependency>*
* <groupId>org.apache.solr</groupId>*
* <artifactId>solr-core</artifactId>*
* <version>${solr.version}</version>*
*</dependency>*
*<dependency>*
* <groupId>org.apache.solr</groupId>*
* <artifactId>solr-solrj</artifactId>*
* <version>${solr.version}</version>*
*</dependency>*
Thanks!
