[quote] Markov Evgeny Igorevich Employee wrote: 1. "Search for products by barcode." https://prnt.sc/x5i4t1. If the product is not found by barcode. Will the standard product search "id" --> "External id" --> "Article" be performed? [/quote] Yes [quote] Markov Evgeny Igorevich Employee wrote: 2. Product search by additional field https://prnt.sc/x5i7t9. If the product is not found for the additional field. Will the standard product search "id" --> "External id" --> "Article" be performed? If more than one product is found by value, which product will be updated? [/quote] not quite, the search by the complementary field comes last, i.e. first by "id" --> "Barcode" --> "External id" --> "Article" and then if not found, then search by additional field the product of which we find first will be updated: we go through the array of the specified additional fields, if there is a value in the file, then we look for this value and try to take the product.

Before importing, all filters from the found products will be removed and the ones specified in the file will be imported instead? [/quote] absolutely all product filters that are being updated will be removed [quote] Markov Evgeny Igorevich Employee wrote: 4. "Overwrite product filter values." https://prnt.sc/x5ifdq. If the product is found during import, will the values of existing filters be updated, and filters that are not in the product will be added? Is the filter search performed by the filter name? [/quote] filter is searched by name you have a filter in your product, for example color. And for example, it says red. Do you have an import file that specifies the color black for this product? If the checkbox is not checked, then the product will have all 2 colors after import: red and black. If the checkbox is checked, then the product will have only 1 color - black if at the same time you will load some kind of filter that the product does not yet have, it will still be added with and without a checkmark
