Yes and no :) Lucene will happily index such drastically different fields, but then, on merge, it will "merge" those two FieldInfos and pick the same configuration for both. For example if one of the fields omitsNorms and the other did not, then on merge, they both will omit norms. Other properties about the field, e.g. whether it was indexed or whether/how term vectors were stored, are not merged/changed because this is a per-document thing. Lucene is often claimed to be "schema-less" but the truth is it effectively has a secret schema that can change over time as merges are done, if you index the same field name differently over time ...
