Limit parameter is not passed to MauiServer

[juhoinkinen]

Maui backend gives at most 10 suggestions even if a larger limit value is set in Annif.

At training time only id and lang parameters are passed to MauiServer, and the default value of 10 is always used for max_topics_per_document.

# http://localhost:8080/mauiserver/tmp-maui-fi/config

id | "tmp-maui-fi"
-- | --
title | "tmp-maui-fi"
description | null
lang | "fi"
stemmer_class | null
stopwords_class | null
cross_validation_passes | 10
max_topics_per_document | 10
probability_threshold | 0

When Maui backend is used in an ensemble project, getting more suggestions would be advantageous.

Good catch! This should be relatively easy to fix - just pass the configured limit value to Maui as max_topics_per_document.

It does mean that the limit used by Maui will be fixed during train time, unlike for other backends where it's applied only during suggest operations. I don't think this is a major problem but could perhaps be noted on the wiki page of the Maui backend.
