---------------------------------------
Summary: SortSpectParsing add null field even the sort direction
if found
Key: SOLR-17311
URL: https://issues.apache.org/jira/browse/SOLR-17311
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: query
Affects Versions: 8.11.1
Reporter: Chatree Srichart
Attachments: null_field_it_set_to_top_vallue.png
Why the SortSpectParsing add null field even the sort direction is found.
When I sort by a child field with a CursorMark:
childfield(groupName_s,\{!parent which='*:* -_nest_path_:*'
v='_nest_path_:\\/customer'}) asc,id desc
The null value will be set to BytesToStringComparator.setTopValue(value) method
which will cause this error:
java.lang.NullPointerException: Cannot invoke "java.lang.CharSequence.length()"
because "text" is null
at org.apache.lucene.util.BytesRef.<init>(BytesRef.java:84) ~[?:?]
Actually the field can be gotten from:
((ChildFieldValueSourceParser.BlockJoinSortFieldValueSource) ((FunctionQuery)
q).getValueSource()).childField
See attached screenshot: null_field_it_set_to_top_vallue.png
Is it a bug?
