The following two screenshots show details of the indices of two search tools.
On the first one you can see the index of the online catalogue of the Trier UAS: All keywords and subject headings starting with the stem "Dampf" ["steam"] are listed alphabetically. With the help of the boxes, a term could be taken over for the catalogue search.
The second screenshot was taken from the interface of the TEMA database. It shows: When entering the expression "Dampfmas..." ["steam eng..."] in the search line, the corresponding index section is automatically displayed. The numbers on the right stand for the respective quantity of hits.
