It's support for upcoming search changes. Items marked for sale can optionally show up there when it goes live, that is how you can toggle it.

ah oke its still "under construction"

Yeah, they made the toggles available ahead of time so that people have an opportunity in advance to hide underpriced or accidentally for sale things from the merchbots that are sure to follow.

If that box is checked, and if the object is also marked "for sale", and if the land the prim is on is also set as "Show in Search Places", then that prim object will be listed in the new search. All three conditions must be met for it to show in the new Search, which has not yet been implemented. The default for the checkbox is for it to be "On" if the item was already for sale and on a listed parcel.

It amounts to free advertizing for anyone who sells the contents of prim boxes, and grossly unfair competition harming anyone who sells from vendor systems.

If you sell the contents of boxes, or copies of rezzed in-world items, then every item you sell can be listed individually in Search, for the low one-time fee of L$30 per week for listing your parcel in Show in Search Places. Even if you have hundreds, or thousands, of items for sale taht will be listed. And most malls are already shown in search by the mall owner, so for all merchants in that mall, it's a completely free way to spam the seach with every variation of every item you sell. I am just praying that the new search will allow some sort of threaded results, so similar entries or entries from the same parcel can be collapsed. Otherwise, finding stuff will be a nightmare.

Meanwhile, those who sell from any sort of scripted vendor system would have to take out a seperate classified ad for each product that they sell, at L$50 per ad, to get the same amount of visibility in Search.

Glad I don't sell scripted vending systems, because the market for them is going straight into the toilet.

In my main store, I sell 75 different items, in three scripted vendors, sorted by class of item. 7 of the furniture items will get a free listing, because I have rezzed copies of those items in-world that are for sale. The rest will show as one random item from each of the three vendors - whatever happenes to be on display by that vendor when their search bot scans the parcel.

So far, it is looking that way. The search results are one line per parcel, rather than per object (the objects are presented as a list on the parcel description page).

The objects' names and description fields are being indexed, so a bit of keyword stuffing in dummy prims made searchable can help alleviate the problem for people who don't have many spare prims to play with.

The flip side of that, of course, is that it will mean a continuation of the same irrelevant keyword spamming we see in the current generation of search. But that part isn't really a new problem I suppose.
