http://lucene.apache.org/java/3_0_3/fileformats.html will tell you all you need to know about what is stored where and how.
In general, the speed of searching i.e. finding matching docs will not be affected by the number of stored fields but retrieving data from lots of stored fields will certainly take longer than retrieving data from fewer stored fields. Only index the fields you need to search on and only store the fields you need to retrieve. If you only need to retrieve some of the stored fields use a FieldSelector. http://wiki.apache.org/lucene-java/ImproveSearchingSpeed has good info on making searching fast. -- Ian.
