--------------------------------------
Summary: SolrCloud MLT does not work with Time Routed Alias (TRA)
Key: SOLR-15615
URL: https://issues.apache.org/jira/browse/SOLR-15615
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: MoreLikeThis, SolrCloud
Affects Versions: 8.8.2
Environment: SolrCloud version: 8.8.2
Reporter: Nahian-Al Hasan
Only the MLT Query Parser works in SolrCloud, otherwise the results returned
are indeterministic (depends on which local shard is hit). However, even with
the QueryParser, MLT throws errors when querying on an Alias. For instance, I
have a unique document like so in a Time Routed Alias:
{
"id":"Bm5bN3KvVitKw5bCcWWCq",
"_version_":1709049415169212416
}
If the MLT Query Parser request with that id, the following error is thrown:
{
"responseHeader":\{
"zkConnected":true,
"status":400,
"QTime":9,
"params":{
"q":"{!mlt qf=name mintf=2 mindf=3}Bm5bN3KvVitKw5bCcWWCq",
"_":"1630550643544"}},
"error":\{
"metadata":[
"error-class","org.apache.solr.common.SolrException",
"root-error-class","org.apache.solr.common.SolrException"],
"msg":"Error completing MLT request. Could not fetch document with id
[Bm5bN3KvVitKw5bCcWWCq]",
"code":400}}
