: No. You can add new documents which will reflect the new schema, but : you can't retroactively update your index. : : In your specific example, it's not possible to losslessly recreate the data : to store from the indexed fields. Consider stopword removal, or lowercasing.
To put it another way: there are in infinite number of changes you can make to the schema.xml which do not *require* reindexing -- but that doens't mean that things will work the way you want them to. You can add (or remove) stored fields, but that won't magically add new data data (or remove to existing data) from any existing documents. -Hoss
