I have a question about like updating the data in Lucene. Supposing

IndexWriter(indexDir, new Analizer(), true); indexaria all the files
again.
absolutely. you'll need to create the logic to do incremental indexing,
but lucene supports deleting and adding documents. an "update" consists
of locating the document to be updated in the index, deleting it, and
re-adding the document.
Although, one should note that this is semantically different from
"updating" a document. Deleting the document and re-adding it results
in the text index IDs changing, whereas a true, in-place update would not.
The ability to do a true, in-place update is like the holy grail of
Lucene. :-)
