Hi,
Since around Lucene 4 (maybe already in 3) there is no way to write
index files in random access anymore. All data must be written in
sequence (aka input stream). This is especially important as Lucene
index files use checksums since around Lucene 5.

nt to just deal with termporary files, the Directory API allows
you to maintain temporary files, too.

Nope, it's embedded completely.
You can find Trie.java in lucene-8.11.2 sources. And compiled class
in lucene-analyzers-stempel-8.11.2.jar as well.

Hi Experts,
As per the definition in

Hi Experts,
We are migrating Lucene from 2.4.1 to 8.11.2.
During Migration for a part of code, we are getting below exception in 8.11.2
based changes from Red line colored.
=
java.lang.IllegalArgumentException: TokenStream fields must be indexed and
tokenized
at org.apache.lucene.do
yLoads on Tokenstreams obsolete. I'd not recommend to use something
payloads on terms nowadays.

On Linux I have no idea, need an exception message. It should clearly
say why it fails.
