A technical problem that kept an unknown number of products out of eBay's search engine index has been fixed, and the e-commerce giant plans to issue credits to affected merchants.

The problem started last Wednesday but eBay didn't acknowledge it until Friday.

The company declared the problem solved on Monday, and advised merchants to not relist affected items, but to instead start a new listing from scratch.

"This week, we will be issuing credits for all items impacted. Please be assured it is not necessary to contact us; we will be issuing these credits automatically," eBay announced Monday in its official Systems Announcements web page.

It's not clear how many products and merchants were affected. eBay has been testing what it calls a "new search experience" in recent months and about two weeks ago the company announced it would directing more traffic to this new engine.

Simultaneously, some merchants have been primarily complaining about the revamped search experience, primarily in an official eBay discussion forum devoted to search in the online marketplace.
