Hi Chris,
So doc.removeFields works fine, just tried it again. You could try using an
approach on the lines of the one mentioned below.
*--snip--*
IndexWriter iw = new IndexWriter(indexDir, new
StandardAnalyzer(Version.LUCENE_30),true, MaxFieldLength.UNLIMITED);
Document doc = new Document();
doc.add(getField(FIELD1, "aa"));
doc.add(getField(FIELD1, "bb"));
doc.add(getField(FIELD2, "cc"));
iw.addDocument(doc);
doc.removeFields("field1");
doc.add(getField(FIELD1, "aaa"));
doc.add(getField(FIELD1, "bbb"));
doc.add(getField(FIELD2, "ccc"));
iw.addDocument(doc);
IndexReader ir = iw.getReader();
IndexSearcher is = new IndexSearcher(ir);
BooleanQuery query = new BooleanQuery();
query.add(new TermQuery(new Term("field1", "aa")), Occur.MUST);
ScoreDoc[] sd = is.search(query, 10).scoreDocs;
for(ScoreDoc scoreDoc:sd){
System.out.println(ir.document(scoreDoc.doc));
}
is.close();
ir.close();
iw.close();
*--Snip--*
