See: https://www.cuba-platform.com/discuss/t/demo-not-woking-fts/6163

Environment

Platform version: 6.9.5

Description of the bug or enhancement

Minimal reproducible example 1) Create a project on the platform version 6.5 2) Enable FTS 3) ReindexAll and ProcessQueue 4) Migrate the project to 6.9, update Db 5) Launch Reindex all or try to search something

Actual behavior The index could not be deleted and FTS also doews not work

org.apache.lucene.index.IndexFormatTooOldException: Format version is not supported (resource BufferedChecksumIndexInput(MMapIndexInput(path="D:\studioSN\2018.08.16\fts65\deploy\tomcat\work\app-core\ftsindex\segments_3"))): this index is too old (version: 5.3.0). This version of Lucene only supports indexes created with release 6.0 and later.

Alternative script: 1) Open https://demo.cuba-platform.com/app/#! 2) Try to search something

The worst problem here is that you can't repair FTS indices without stopping the server. You have to:

stop the server
delete indices from the disk (rm -rf $tomcatDir/work/app-core/ftsindex)
start the server and reindex from scratch.

This is very inconvenient.
