Hi, Changing schema will not do anything by itself. After changes are applied (core reloaded if not used API to update schema) it will use new schema to index new documents. What matters is what you had in index before schema updates. So if you had defined Field_one as string or you had it as number but never used that field, deleting it and letting dynamic field handle from that moment should be fine. Similar goes with adding new field - if you are adding new definition for Field_100 before you used it, it will be ok.
