Public Methods

Method Description
CreateWeight ( Query original ) : Weight

Create weight in multiple index scenario. Distributed query processing is done in the following steps: 1. rewrite query 2. extract necessary terms 3. collect dfs for these terms from the Searchables 4. create query weight using aggregate dfs. 5. distribute that weight to Searchables 6. merge results Steps 1-4 are done here, 5+6 in the search() methods

Doc ( int n, Lucene.Net.Documents.FieldSelector fieldSelector ) : Lucene.Net.Documents.Document
DocFreq ( Lucene.Net.Index.Term term ) : int
Explain ( Weight weight, int doc ) : Explanation
GetSearchables ( ) : Searchable[]

Return the array of Searchables this searches.
MultiSearcher ( ) : System

Creates a searcher which searches searchers.
