You might be aware that eBay had a glitch on Friday that prevented some listings from being included in the Search results.   The issue is now resolved and all items should be properly included in eBay Search results.   If you were one of those sellers, be sure to follow-up with eBay because they will be issuing credits for those listing fees. 
 
eBay is recommending that you do not relist those items, but create a new listing, if the item ended without a buyer.  Here is the announcement:
 
eBay informed sellers on Friday of a glitch that prevented some listings from showing up in search results. The company followed up Monday morning
 
This issue has been resolved, and all items should be appearing in Search as usual. If one of your items was impacted, it would be best to NOT relist it, but rather 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.

Thank you for your patience while we resolved this issue, and we apologize for any frustration or confusion it caused.
