The point is that I can't get the browser to display all the cards in the deck. I can search for individual notes, but if I try to show the whole deck (over six hundred cards) I can only get 55 of only one of the three card types.
They're not showing up because they're not in the deck you're searching in. I suggest you search for the cards using the note type, then move any that are in the wrong place into the place you expect them to be.
OK, so I verified this is correct. But a comment on the guide: Recommends "Edit→Select Notes" which wants me to put nid:______ in the browser search. Putting the name of the note type gets "Invalid search." I have no way of determining the note ID. But if I use the filter button, I can pick the name of the note type from a menu (and it is exactly what I tried to type in as the mid).
Now I have them where I want them. But it still raises questions. I selected all the notes in the deck and removed them. Filtering to that deck showed it was empty. Then I selected Import, selected the 257-line file, made sure the deck and note type was correct, and was told 257 notes added. How did one card type on 55 of 257 go into the correct deck while the other 202 notes and 110 cards go elsewhere? This was a new note type; not previously in any deck.
Sorry, which guide are you referring to? The simplest way to see all cards of a note type is to click on the note type in the left bar of the browser - which if it's not hidden, can be revealed by choosing the sidebar option in the filter button.
When you import or edit a note and that causes new cards to be generated, if Anki is not sure which deck they should be placed in, they are placed in the default deck.
“When you import or edit a note and that causes new cards to be generated, if Anki is not sure which deck they should be placed in, they are placed in the default deck.”
I select File→Import and select a text file. In the pop-up, I change both “Note” and “Deck” to “WorldFlags”. The next pop-up says 257 notes added. How can 55 cards of one type go into the Deck I selected, and 202 of that type plus all of the other two types go into the Default deck? (Which was apparently re-created, as I had previously deleted it.)
Importing will not change the location of existing cards. The cards that are already in your collection stay where they are, and the new cards are placed in the location Anki thinks they belong. This can change based on the deck you've selected and any deck overrides for individual templates, and if Anki is not sure, the cards end up in the catch-all default deck.
