I sometimes have bad search days. I think it might be related to ultrapeers you're connected to.

Go to LW's menu bar, View menu -> Show Hide Connections. Then right-click heading bar & tick option to show vendor/version. Select one (if any) that are not LW version 4.18, then press Remove button at bottom of window. Even if all 4.18, select one anyway & do that. Now wait for LW to find another ultrapeer to connect to .. wait until LW stabilizes its connection. Then go & try a search again. You may need to repeat this process.

The thing about how LW works is .. a search will only find a certain % of the entire network. It therefore depends on ultrapeers you are connected to to get results you are looking for.

Keep in mind also, some ultrapeers are actually spammers & some are just poor functioning ultrapeers.

When I went to connections, there were no entries at all under "Vendor/Versions". At the top of the graph it read:

"0 Ultrapeers, 0 peers, 0 Leaves, 10 connecting, 0 Standard"

So it looks like, for some reason, my LW is not connecting with any peers.

After I posted my last note, I left LW on in the background and went about doing other things online. When I went back to LW, there were well over a dozen Ultra-peers showing. I guess it sometimes takes awhile for LW to locate them? I don't recall that happening in the past. Has something changed in the LW software or procedures?
