Allow field names for manual index

Enhancement request.

If we can label the fields making up the key in a manual lucene index, it will make the search capability more versatile.

See Issue 27

Could you elaborate more your request? Maybe writing down a pseudo-SQL or Java statement and expected results. Thanks

Suggested use from @wouterv initial issue

create index index_name ('id','name') FULLTEXT ENGINE LUCENE STRING, STRING

Then be able to insert like

insert into index:index_name (id, name, rid) values (1, 'jeff', #45:0)
insert into index:index_name (id, name, rid) values (1, 'Luca', #45:0)
insert into index:index_name (id, name, rid) values (2, 'Luca', #45:1)

and then query stuff like

select * from index:index_name where [id, name] LUCENE "(id:1 OR name:Luca)"
