Thank you for your answer Grant.
I already have a similar architecture than yours, allowing me do
retrieve the analyzer used for a specific index.
But how does it solve the problem of doing one search on multiple
indices using multiple analyzer ?
I'm not sure I was enough clear when asking my question.
Currently here is what can be done using the MultiSearcher;
// let's pretend for the example that we deal with two languages index,
// Directory indexDirEn, Directory indexDirEn;
Searcher[] searchers = { new IndexSearcher(indexDirEN), new
IndexSearcher(indexDirFR) };
MultiSearcher searcher = new MultiSearcher(searchers);
Query query = QueryParser.parse(queryStr, "defaultfield", theAnalyzer));
Hits hits = searcher.search(query);
As you can see, we user the same analyzer "theAnalyzer" for all indices,
this is of course a bad idea because each of the indices have been fill
using a dedicated analyzer.
What I'd like to do is more something like this:
Searcher[] searchers = { new IndexSearcher(indexDirEN), new
IndexSearcher(indexDirFR) };
Analyzer[] analyzers = { enAnalyzer, frAnalyzer };
MultiSearcher searcher = new MultiSearcher(searchers);
Query query = QueryParser.parse(queryStr, "defaultfield", analyzers));
Hits hits = searcher.search(query);
(I undesrstand this code makes no sense, it's just to show that I want
to specify as many analyzer as there are indices).
Any suggestions?

I store an Index (not part of Lucene) object w/ the Lucene index that
contains a bunch of metadata about the index, one being the name of the
Analyzer used (other things include the language of the Index, which
field contains a unique document identifier (not the internal Lucene
id), etc. Then at search time, I just get an new instance of that
Analyzer and pass it to the query parser and do my searches. Then you
just need a mechanism for managing your Index, which is pretty
straightforward (hash by location or something like that)
