If I understand correctly, you want an arbitrary number of related addresses, retrievable separately, but searchable simply as:

address:"my address"

I would recommend storing addresses named whatever you like (I will use 'address1' and 'address2' here), and accumulating their text into one big old 'address' field. Something like:

doc.add(new Field("key", "1", Field.Store.YES, Field.Index.ANALYZED));
doc.add(new Field("name", "sam", Field.Store.YES, Field.Index.ANALYZED));
doc.add(new Field("address", "lane no 1 behind la gardens near abc cross main road", Field.Store.NO, Field.Index.ANALYZED));
//Note, that you can add multiple fields with the same name, and it will effectively be merged together, as:
doc.add(new Field("address", "more address information for searching", Field.Store.NO, Field.Index.ANALYZED));
doc.add(new Field("address1", "lane no 1 behind la gardens", Field.Store.YES, Field.Index.NO));
doc.add(new Field("address2", "near abc cross main road", Field.Store.YES, Field.Index.NO));

Note that address is passed Field.Store.NO and Field.Index.ANALYZED, while address1 and address2 are passed Field.Store.YES and Field.Index.NO. So you search on 'address', but never on 'address1' or 'address2', and you retrieve 'address1' and 'address2' from found documents, but never 'address'

Document temp = new Document();
temp.add(new Field("name", "sam", Field.Store.YES, Field.Index.ANALYZED));
temp.add(new Field("address", "lane no 1 behind la gardens", Field.Store.YES,
                   Field.Index.ANALYZED));
indexWriter.addDocument(temp);

搜索喜欢

name:sam address:gardens

将导致匹配上述文档
