As a Wikipedia user I want to be shown a hint if there are any search limitations so that I know that the number of searched categories is limited due to technical reasons.

As a Wikipedia user I want to be offered the option to hide the hint for the next search so that I don’t need to read it all over again each time I use the deepcat gadget.

The hint should be shown again if the text changes (= if the limitation changes). The hintbox should appear after the user typed "deepcat:" and once he starts to type the keyword (purpose: the user knows that there are limitations before he hits "enter" and gets the search results)

Hint box text for the search at "https://de.wikipedia.org/w/index.php?search":

"Momentane Einschränkung pro Suchbegriff:
Max. Kategoriensuchtiefe: 10 / Max. Kategorienanzahl: 50
[LINK] Diesen Hinweis zukünftig ausblenden."

The hint box should be in a different colour than the rest (blue).

While showing the hint box under the small search field (in the upper right corner of the site, e.g. "https://de.wikipedia.org/wiki/Wikipedia:Hauptseite") the text should be shorter:

"Max. Kategoriensuchtiefe: 10
Max. Kategorienanzahl: 50"

Once the user gets the results (which are displayed at "https://de.wikipedia.org/w/index.php?search"), the longer text with the option to hide the hint should be displayed.
