For example, if the first document has a field with value "0", it is guessed as Long and subsequent fields with "0.0" are rejected. Similarly, if the same field had alphanumeric contents for a latter document, those documents are rejected. Also, single vs. multi valued field guessing is not ideal. > Proposing an offline training mode where Solr accepts bunch of documents and returns a guessed schema (without indexing). This schema can then be used for actual indexing. I think the original idea is from Hoss. > I think initial implementation can be based on an UpdateRequestProcessor. We can hash out the API soon, as we go along. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscribe@lucene.apache.org For additional commands, e-mail: dev-help@lucene.apache.org
