Try and index one special term per document (e. g. score:pagerank), and index one position with a payload for each doc. Then when you retrieve hits open a TermPositions using the special term, get the payload and incorporate it in the docs' score. The performance overhead should be comparable to adding one AND-term to your query. -Michael > On 11/15/07, Zhou Qi <[EMAIL PROTECTED]> wrote: > >> Thank you, my score is fixed score from the properties of the page, but at >> first we need to adjust the score for a promising result. >> I have tried one way of manually re-ranking all the documents by the >> search results.
