Description

With Elastic, a query without a root node (ISDESCENDANTNODE(...)) is returning a maximum of 5 results. See the Elastic version of the test in org.apache.jackrabbit.oak.plugins.index.IndexDescendantSpellcheckCommonTest.noDescendantSuggestsAll.

Also see other ignored tests in - 

(oak-search/src/test/java/org/apache/jackrabbit/oak/plugins/index/IndexDescendantSpellcheckCommonTest.java)

This seems to be related to:

https://discuss.elastic.co/t/elasticsearch-suggestion-completes-return-incorrect-number-of-suggestions/214522

Even increasing the suggester query size the number of max results seems to be fixed to 5.
