i have a curiosity

when a document is updated or deleted , lucene must update inverted table.
considering the size of record about a specific term (before used) is
changing ... how lucene resave term record?

Lucene only marks documents as deleted, it keeps the inverted index as-is.
Deleted terms are only expunged at merge time since Lucene ignores terms
that only match deleted documents.
