Trying to use solr

Hi,

I am finally trying to use an fts engine with dovecot. My version is 2.3.7.2 under Ubuntu 20.04.

I installed solr 7.7.3 and then 8.6.0 to see if this was a version-related error. I copied the schema from 7.7.0 as many people said this was fine.

I get the following error when trying to reindex a user's mailbox:

doveadm(francis@francisaugusto.com): Error: fts_solr: Indexing failed: 400 Bad Request doveadm(francis@francisaugusto.com): Error: Mailbox INBOX: Transaction commit failed: FTS transaction commit failed: backend deinit doveadm(francis@francisaugusto.com): Debug: auth-master: conn unix:/var/run/dovecot/auth-userdb: Disconnected: Connection closed (fd=10)

On Solr I get this error:

org.apache.solr.common.SolrException: Exception writing document id 210/9fd7941e8297d25d91600000c3fdd3da/francis@francisaugusto.com to the index; possible analysis error: cannot change field "box" from index options=DOCS_AND_FREQS_AND_POSITIONS to inconsistent index options=DOCS at org.apache.solr.update.DirectUpdateHandler2.addDoc(DirectUpdateHandler2.java:246)

Parallel to this, I got some log messages on Solr before attempting to reindex the user (sorry for the garbadged text:

Could anyone point me the right direction to make this work?

Best,
