Minimal Solr score for inclusion in results?
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty height:90px;width:728px;box-sizing:border-box;
I have created a collection of medical terms, using all default Solr (7.5) settings. The documents came from CSV files and I used bin/post with default settings.
When I submit a silly query I may not get the number of rows I have requested.
http://host/solr/collection/select?fl=anyLabel,score&q=anyLabel:(astronaut%20%20football%20felafel)&rows=9999&wt=csv
Is there some score threshold? In this case, the lowest score is ~ 8. I've run other less-silly queries that return reasonable results down to scores of 2 or 3.
Why was this result truncated after a result with a score of 8? Do I have any control over that?

There is no minimum score - anything above 0 is considered a match in some way, and is included as long as the rows and start parameter make sense compared to the numFound value in the response.
In general scores are not comparable between requests, and extrapolating scores to mean "a document with half the score of another document is just 50% as relevant" does not make sense either.
The score will also depend on the similarity algorithm used, which can differ between Solr versions. For 7.5 it's a BM25 Similarity.
