Effective indexing requires strict application of a defined schema rather than descriptive labelling based on individual judgment. Every operator working on the same index should produce the same index entry for the same record. When indexing is inconsistent, search results become unreliable — some records are found and others are not because they were indexed differently by different operators on different days.
We review your indexing schema, controlled vocabulary, field definitions and output system requirements before production begins. A pilot indexing batch is produced for your review to confirm that classification decisions, vocabulary application and output formatting are correct before the full project is committed.
