Have you considered combining the AnalyzingInfixSuggester with a German
decompounding filter? If you break compound words into their
constituent parts during analysis, then the suggester will be able to do
what you want (prefix matches on the word-parts). I found this project
with a quick google search:
https://github.com/jprante/elasticsearch-analysis-decompound; I don't
know how good it is or whether it fits with your environment, but it
could be a start.

Hello,
I'm looking for an infix suggester that allows infix search for a given
term. This might not be that important in English.
However in German we have quite complex composite words like
Donaudampfschifffahrtsgesellschaftskapitän
which is composed by the nouns Donau (danube), Dampf (steam), schiff
(boat), etc.
So I would like to support searches like *schiff* to suggest
Donaudampfschifffahrtsgesellschaft.
I have mistakenly tried for the AnalyzingInfixSuggester, however this
does not do what I expect, because it does prefix matches to tokens, but
no infix matches.
I tried to adapt the AnalyzingSuggester, however it seemed to complex
for an easy conversion to an infix suggester.
I know that this was already asked by

however, nobody answered this post as far as I know.
Thank you for your help
