Search for multiple indexes in Lucene.Net

Question

I have several lucene.net indexes that I will need to search for the query string. So will I need to open a new IndexSearcher for all of these indexes, or can I achieve this with a single IndexSearcher?

thanks

Answer 1

This can be done using MultiSearcher .

It implements the Searchable interface for several researchers. If you only need methods from the Searchable interface, it will look like a regular IndexSearcher.

If you need to access the main search engines that found the document, you can use the subSearcher(int) and subDoc(int) methods.
