Selects documents that contain specified values in one or more document zones. A document zone represents a region of a document, such as the document’s summary, date, or body text. The IN operator only works if document zones have been defined in your collections. If you use the IN operator to search collections for which zones are not defined, no documents will be selected. In addition, the zone name you specify must match the zone names defined in your collections. Consult your collection administrator to determine which zones have been defined for specific collections. The example in “Sample topic outlines” shows how IN might be used with the word “sculpture” and the TITLE zone.
