When I'm attempting to exhaustively go through all the search results for a particular publisher, say, the page navigation bar at the bottom sometimes changes wildly as I page through.
Here's an example:
I first clicked on Wordsearch as the publisher (on some other book I was looking at).
Then I chose facets to shape the results: Unowned, Geographic Availability = All, and Live. Sort by Price (lowest first).
Here's the URL for the search results:
https://www.logos.com/search?filters=publisher-7834_Publisher%2Bstatus-live_Status&sortBy=PriceLow&limit=60&page=1&ownership=unowned&geographicAvailability=all&useFuzzySearch=false&viewMode=list
Page 1 of the results looked reasonable. A total of 479 Results. The navigation bar at the bottom looked like this:

I clicked to go to Page 2, and the total number of results shrank to 358.

I clicked to go to Page 3, and the total number of results changed to 391.

I clicked to go to Page 4, and the total number of results changed to 514.

I clicked to go to Page 5, and the total number of results changed back to 391.

I clicked to go to Page 6, and the total number of results stayed at 391.

I clicked to go to Page 7, and the total number of results changed to 467.

I clicked to go to Page 8, and the total number of results went back to 391. But I was told I was viewing results 301-360 again, with no page highlighted and no way to navigate to the next chunk.

In addition to the above weirdness, I noticed the certain books were showing up again on later pages that I'd already seen on earlier pages.
No doubt this is all related to the emphasis on getting the first page of results quickly and not caring about the accuracy of later pages of results. But this is the way I always used to look for more books I might want to buy. If I can't do that in a way that works, I'm likely going to stop buying books, unless something happens to come across my radar that I'm interested in. But when I've already got over 30K books, how do books I don't own "come across my radar"?
You need to do a better job of serving people with large libraries if you want to keep getting revenue from us.
