Hi, There are few stages:
1. Set in nutch-site.xml the property: fetcher.store.content to false. 2. Write a parse filter which will set some metadata variables during parse stage like the description 3. Write a index filter which will add your description variable to the index (or replace the content field in doc to your variable) If you will have many fields you will have to add also a query filter.
