Li Enlai created SOLR-18329:
-------------------------------
Summary: DenseVectorField should support existence queries
(field:* / [* TO *])
Key: SOLR-18329
URL: https://issues.apache.org/jira/browse/SOLR-18329
Project: Solr
Issue Type: Improvement
Components: Schema and Analysis
Reporter: Li Enlai
Lucene has supported existence checks for vector fields since 9.1
(KnnVectorFieldExistsQuery, later unified into FieldExistsQuery).
Solr's DenseVectorField currently rejects these queries with BAD_REQUEST.
Proposal:
- Support normal existence queries on DenseVectorField:
- vector:*
- -vector:*
- vector:[* TO *]
- Implement via FieldExistsQuery in DenseVectorField.getExistenceQuery()
- Keep rejecting bounded range queries (unchanged)
This is a small consistency fix so DenseVectorField behaves like other
field types for existence checks.

I have a local patch with tests ready and can open a PR.
