Multi Index Search Query
Hi,
I have two index files. I am searching id1 from Index A and id2 from Index B.
By using id1 (Index A) results , I am searching id2 from Index B. I stored these two index files in local file system.
I am using filter as a result of Index A.
IndexSearcher.search(Query,filter,10000);
I am running queries individually. Is there any possibility that I can combine these two queries into single query. Can I use Multi index search in this case ?

This is usually something you should not do. Is there any possibility you can
combine these indexes into one? Maybe sharded? Because this approach
is almost guaranteed to scale poorly.
This smells like an XY problem, perhaps you can back up and explain
what the higher-level problem you're trying to solve is...

If you actually intend at getting the intersection of 2 results from a
'union' of 2 indexes, you could use the filter and query approach. You could
use a multi searcher or a parallel multi searcher to perform the search in
this case.

Hi all,
I have the same problem with Madhu, that i want to search over multi indexes
and over different fields.
Example: my search text: "lucene multi indexes",
i want to search in index A (field: content1) and B (field: content2),
and the each result must contains "lucene multi indexes".
I tried to use MultiSearcher but I found that MultiSearcher returns the "OR"
results not "AND"
Dose any one know how lucene can do it? or suggest me another way to do it?
Thanks,

I don't think so, you could combine the queries. You are first searching
Index A and the results are given as input to Index B. You cannot combine
the queries and you cannot use multi searcher or parallel multi searcher.
You need to search two indexes independently and sequentially.
