searchField names the field the search box looks at, which no longer has to be the field the list groups by.

Three definitions carry the split:

• groupField is bibtex-entry-type, so the groups and the tabs are publication types
• searchField is bibtex-author, so typing still matches people
• f.tiddlersMatching narrows the tiddlers first, and the groups are derived from whatever survives

Because the groups are computed after the search, a whole group disappears once none of its entries match. The tab strip is still built from the unfiltered data, so the tabs themselves stay put.

This test case carries the same _TabButton and _TabContent payload tiddlers as the previous example.

Type bar to leave only InProceedings, holding Barker's two papers. The other tabs drop to zero and show the emptyMessage of the list.
