What is it all about?

Lucene scoring uses a combination of the Vector Space Model (VSM) of Information Retrieval and the Boolean model to determine how relevant a given Document is to a User's query. In general, the idea behind the VSM is the more times a query term appears in a document relative to the number of times the term appears in all the documents in the collection, the more relevant that document is to the query.

Key Features

1. The Weight object of the Query. The Weight object is an internal representation of the Query that allows the Query to be reused by the Searcher. 2. The Searcher that initiated the call. 3. A Filter for limiting the result set. Note, the Filter may be null. 4. A Sort object for specifying how to sort the results if the standard score based sort method is not desired.
