In this case, an example might be the easiest way to explain this tweak. Take a look at this search of San Luis Obispo, CA, sorted alphabetically. The #2 entry is for the "Beach Vacation Series"--the quotes are part of the box name, not me quoting the box name. In the old days (that is, before today), Atlas Quest would sort boxes on a character-by-character basis, and because quotes come before letters, it would have shown as the first box. Now, quotes (and other punctuation marks) are ignored, so the box is now correctly placed after the A from All the News That's Fit to Print.
A related issue are box names that start with "useless" words--the, and, a, etc. In the old days (that is, before today), a box named The Building would have been sorted under the T's. If you check those search results, however, you'll now see it listed along with the other B's, where it should be.
Number 12 in the search results is called A Dragon in the Library: Adelinde. In the old days, it would have shown up in the A's. Today? Nope, not anymore.... It's with the other Ds.
Because punctuation marks are ignored, you'll also find that words like dogs and dog's map to the same word pattern. In the old days, a search for either of those words wouldn't find both of them. You can see this happen in a global search for boxes with the word dogs. In my results, the first six use the word dogs, but #7 uses the word dog's.
In another slight tweak in the search results, in this search for Winter Falls, you'll find none of the first several entries use the word winter. Why would they rank so highly, then? Because it's part of a series, and one of the boxes in the series use the word winter. If you click on the Silver Falls series, it ranks highly because there's a box within the series named Winter Falls. In the old days, AQ was not able to match words in the names of individual boxes within a series--but now it should!
Anyhow, these are minor little tweaks, but I'm a little concerned I've overlooked something. If you happen to notice any search results that aren't quite as expected or find an unexpected glitch, do let me know! Thanks! =)
