-------------------------------------
Before saying this ends up in Apache Lucene land - I see that
https://github.com/apache/lucene/issues/12021 was already opened there. I'm
going to update the links above to point to the Apache Solr code.
> Large fields with large="true" can be truncated in v9+
> ------------------------------------------------------

> Key: SOLR-16589
> URL: https://issues.apache.org/jira/browse/SOLR-16589
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: search
> Affects Versions: 9.0, 9.1, 9.2
> Reporter: Nikolas Osvalds
> Assignee: Michael Gibney
> Priority: Major
>
> h3. Summary
> For fields using large="true", large fields (which is what they are intended
> for) can be truncated in v9+ of Solr.
> Example fieldtype definition:
> {code:java}
> <fieldtype name="string_large" class="solr.TextField" multiValued="false"
> indexed="false" stored="true" omitNorms="true" large="true" />{code}
> Cause
> Looks like this is a bug introduced along with
> https://issues.apache.org/jira/browse/LUCENE-8805) /
> [https://github.com/apache/lucene/issues/9849|https://github.com/apache/lucene/issues/9849:]
> [https://github.com/apache/lucene/blob/5a694ea26ff862ecc874ca798135073d300c2234/solr/core/src/java/org/apache/solr/search/SolrDocumentFetcher.java#L462-L465|https://github.com/apache/solr/blob/bc2d9623f7960f83636eb8416b11dd4e91ab4b22/solr/core/src/java/org/apache/solr/search/SolrDocumentFetcher.java#L508-L511]
>
> {code:java}
> public void stringField(FieldInfo fieldInfo, String value)
> throws IOException {
> Objects.requireNonNull(value, "String value should not be
> null");
> bytesRef.bytes = value.getBytes(StandardCharsets.UTF_8);
> bytesRef.length = value.length();{code}
>
>
> Specifically with respect to "large" fields handling.
> The length in utf8 bytes will often be longer than the string length
> `value.length()`, hence the truncation.
> h3. Fix
> The Fix would be:
> {code:java}
> bytesRef.length = bytesRef.bytes.length {code}
>
