I have multiple lucene.net indexes that I would need to search on for a query string. So will I need to open a new IndexSearcher on all these indexes or can I achieve this with a single IndexSearcher?
Thanks

It can be accomplished using the MultiSearcher.
It implements the Searchable interface over multiple subsearchers. If you only need methods from the Searchable interface it will be just like a regular IndexSearcher to you.
If you need to access the underlying searchers that found a document, you can use the
subSearcher(int)andsubDoc(int)methods.http://lucene.apache.org/java/2_9_4/api/core/org/apache/lucene/search/MultiSearcher.html
