indexed products do not appear in the search engine

[nacxo]

Hello everyone,

I would like to know if someone can help me with the following:

I have a loan with 9000 products (all indexed according to the "Search" area) that were initially downloaded from another web. The problem is that there are old products that are not found in the search engine of the web.

I have proven that if I assign these products "HOME" as the default category, they appear in the search engine. (in fact if I return to the default category they had now if they leave)

How can I do to not have to do this process with each product one by one? Do you get something?
