#### Configuration Migration

Map Solr configuration to Fess:

| Solr Feature | Fess Equivalent |
|--------------|----------------|
| Solr Core | Fess doesn't use cores; all documents in one index |
| Schema Fields | Define in crawl configuration or use default fields |
| RequestHandlers | Use Fess JSON API with parameters |
| Facet Fields | Configure in Fess search settings |

## Version 4.6.0

 *  Fix: Follow HTTP 307 and 308 redirects on methods other than GET and POST. We're reluctant to
    change OkHttp's behavior in handling common HTTP status codes, but this fix is overdue! The new
    behavior is now consistent with [RFC 7231][rfc_7231_647], which is newer than OkHttp itself.
    If you want this update with the old behavior use [this interceptor][legacy_interceptor].
