Our site's built-in search feature is managed by Google, so we honestly don't have much control over it. They revisit our site on about a weekly basis, so it may take that long for any new product listings added to Marketplace to show up in search results on our site. Also bear in mind that you must be paying for an active subscription in order for items listed in your E-junkie Shop to also appear in the general E-junkie Marketplace. Although a search on our site is supposed to return all the same results as a regular search on Google.com, lately we've noticed that a search on our site returns a lot fewer results than performing the same search on Google.com, so we've been trying to work with Google to get that sorted out.
Rest assured this doesn't really affect sales, since buyers don't really use our site's search function anyway. We are not a major "online shopping mall" destination like Amazon or eBay, so buyers really don't just show up on our site with cash in hand looking for stuff to buy. Almost all purchases made from E-junkie Shops and Marketplace happen when the buyer arrives directly at a specific product's or seller's page. This is usually because the buyer found that product's or seller's page from a search they ran on Google, Yahoo, etc., or as a result of the seller's own online marketing or advertising sending buyers directly to their product or Shop page.
