Fixed

• search keeps the query's fields for documents found by meaning. tag:work or date>=30d without --exact
  returned about 20 documents that matched neither; now every field and every excluded word holds for every hit, and
  a query of fields alone lists the matching documents, newest first. date: reads a document's last edit on Google
  Drive, the time its hit shows as updated_at, where it read when drive last imported it (cli-core 0.496.0).
