Description

IndexWriter can update doc values for a specific term but this might
affect all documents containing the term. With tryUpdateDocValues
users can update doc-values fields for individual documents. This allows
for instance to soft-delete individual documents.
The new method shares most of it's code with tryDeleteDocuments.
