A general search for 1/24 only finds a fraction of the appropriate items [résolu]

When I search in German States for “1/24” only ten results are returned, but there are many more listings that should be included. Searching German States face value for 1/24 returns 455 items, and the general search should return at least that many.

Other searches are broken as well. For 1/48 a general search shows only 7 results while a face value search shows 115.

Are general searches not searching the face value field after the recent change in how denominations are stored?

On the other had ½ doesn't show the same problem. There are more results from a general search than from a face value search. (Which doesn't mean that some pages aren't missing.)

This specific problem seems to have been fixed, but there are still other problems with searching for fractions.
