Why does help center search miss non-English words, and can search be turned off?
Help center search matches whole words using English language rules, so searching for part of a non-English compound word returns no results. The search widget itself cannot be turned off.
Why non-English keywords return no results
Plain indexes each word as a single term and stems it using English rules only. German and other non-English compound words are stored as one term. For example, "Jobvorlage" is indexed as one word, not as "job" and "vorlage". A visitor who searches for "job" sees "No search results" even though articles visibly contain that text.
Instead, search for the full word as it appears in the article title or body, such as "Jobvorlage" rather than "job". Shorter queries only return results when they exactly match a stored word. Partial matches inside compound words are not supported.
Can the search widget be disabled?
No. The search widget on the help center home page is part of the core layout. There is no option in your help center's Appearance or General settings to hide or remove it.
