Hi,
I am a newbie to Lucene. I have a question for making a query that associate
2 index files:
- One index has the content index for a list of documents and a key to the
document. That means the Lucene document of this index contains 2 fields:
the 'content' and the 'key'.
- another index has the some data indexed associated with the 'key' in the
previous index. The Lucene document of this index contains several fields:
the 'who' that contains some data and the 'key' that _points_ to the
document in the first index.
Sample data:
Index_1: [key] [content]
Abc "blah blah 123 ..."
Xyz "123 321 a nice day ..."
Index_2: [who] [accessed] [key]
David 1/1/2007 Abc
Someone 1/2/2005 Abc
Guess 12/1/2000 Xyz
Harry 1/1/2008 Abc
Sandra 1/1/2003 Xyz
As shown, the [key] field in Index_2 has repeated value that _points_ to the
[key] values in Index_1. How do I make a query for the following:
Find out all documents in Index_2:
- [who] is in range of 'David' to 'Guess' and
- [accessed] in range '1/1/1900' to '1/1/2010' and
- [key] associated [content] in Index_1 that contains the term 'blah'
I know this is more SQL like query. Is Lucene capable of doing this type of
query that needs associations among index files?
Thanks in advance.
