I have a couple of custom fields associated with products. How can I extend the functionality of search so that it also searches if the query text is contained in the custom fields of any product. I need an OR relation, i.e., query text is in either product name, custom field 1, custom field 2.
I read another question in this forum for the same. However, the links were broken and the ProductSearchKeywordIndexer it referred to seems to be depreceated. Could you please tell me how to solve this issue?
