A full-text index is a collection of managed properties that are searchable as a group. Managed properties are mapped into one or more full-text indexes through GetFullTextIndexMappings(). The relevance contribution of managed properties can be tuned by mapping managed properties to a full-text index at different importance levels. The default full-text index is searched when no full-text-index is specified in the query.
