An eBay domain to search in. This is like searching a section of the eBay catalog. If this field is not included, the catalog product search is conducted across all defined eBay domains. The user can use multiple DomainName filters to search multiple defined eBay domains. If you are using a URL, and you want to specify multiple values, use an index value (not a comma). For example, to specify DomainName=Textbooks,Education, specify DomainName(0)=Textbooks,%20Education. To retrieve valid domain names, first use this call with your query string specified in QueryKeywords, and the IncludeSelector field's value set to
DomainHistogram. After retrieving all eBay defined domain names for the query string under the DomainHistogram container, the user can select the eBay domains relevant to the product they're searching for, and then they can do another FindProducts call with one or more DomainName filters.
Generally, DomainName filter(s) are only useful for query string searches using QueryKeywords field. If you are searching for a specific catalgo product based on eBay Product ID (ePID) or a Global Trade Item Number (GTIN), such as a UPC, ISBN, or EAN, a lt;b>DomainName filter is not needed.
