Hi,
Thanks for your advise, SimpleQueryParser api is not enough in my case.
Actually, I want to index data from database, there are so many fields, I have
tested "_all" parameter in ElasticSearch system, but the result of '_all'
and 'fieldname' are different for chinese term.
'Internally this is indexing every field a second time into the "_all"
field.'
This sentence mean second indexing has total different analyzer and indexing
compared
with my first indexing? So I need rewrite the second process to fix my problem?
Thanks.
