Description

When cursorMark pagination is used together with elevateIds, an exception is thrown.

 

Steps to reproduce described below.

 

1. Start solr with the `demo` core

docker run --name solr_cursor_elevate -d -p 8983:8983 solr:7.2 solr-demo

 

2. Add some test documents

curl http://localhost:8983/solr/demo/update?commit=true -d '
[
{{ {"id" : "book1",}}
{{ "title_t" : "book one"}}
{{ },}}
{{ {"id" : "book2",}}
{{ "title_t" : "book two"}}
{{ },}}
{{ {"id" : "book3",}}
{{ "title_t" : "book three"}}
{{ }}}
]'

 

3. Execute a query with cursorMark and elevateIds

curl 'http://localhost:8983/solr/demo/elevate?cursorMark=*&elevateIds=book3&enableElevation=true&df=title_t&fl=id,title_t&forceElevation=true&q=book&rows=2&sort=id%20asc'
