When QueryParser is set to "Don't try", "QueryAutoTruncation" will turn off
relevance searching if it's set to "automatically". 

However, relevance searching shouldn't be affected by "QueryAutoTruncation"
when QueryParser is set to "Try".

I suspect...that your result might be coincidence, Katrin. With the
QueryParser, it applies relevance to your search query as well as adding
relevance subqueries for title keyword and title exact.

Since you're using "DE-576" as your search term, you'll probably get no hits
for title keyword or title exact, so the relevance "bumps" become irrelevant.

Then, for the results you do get, I suspect that "DE-576" would only show up
once in a record so each record retrieved would have the same relevance score.
Since the search term is quite specific, Zebra will probably only return
records with that exact search term so you won't get anything "less relevant".

tl;dr

Katrin, could you try again but using a more vague search term? Something that
is likely to appear in a lot of different records with different frequency?
Probably a noun. I often like to use "health" or "test" as we have a lot of
medical records.

I might be wrong, but...I think that's the most logical explanation for your
results.
