Marc Linden updated SOLR-14662:
-------------------------------
Description:
When performing a distributed search with multiple shards having elevation
configured where one ore more shards do have elevated results but others do not
a NullPointerException is thrown.
We are using Solr 8.2 and have the QueryElevationComponent configured with
"last-components" of the default search handler "/select". But the problem also
occurs when using the explicit "/elevate" search handler.
{code:xml}
<requestHandler name="/select" class="solr.SearchHandler">
...
<arr name="last-components">
<str>elevator</str>
</arr>
</requestHandler>
...
<searchComponent name="elevator" class="solr.QueryElevationComponent" >
<!-- pick a fieldType to analyze queries -->
<str name="queryFieldType">string</str>
<str name="config-file">elevate.xml</str>
</searchComponent>
{code}
h3. Steps to reproduce:
(1) Add entries to the elevate.xml of each core to elevate a specific document
for the text "elevatedTerm
{code:xml}
core1:
<elevate>
...
<query text="elevatedTerm"><doc id="core1docId1" /></query>
</elevate>
core2:
<elevate>
...
<query text="elevatedTerm"><doc id="core2docId1" /></query>
</elevate>
{code}
(2) Execute query (we use port 9983)
{noformat}
http://localhost:9983/solr/core1/select?q=elevatedTerm&lowercaseOperators=false&df=text_en&defType=edismax&fq=lang:en&shards=localhost:9983/solr/core1,localhost:9983/solr/core2&fl=[elevated],[shard],area,id&rows=10&start=0
{noformat}
As both shards have elevated documents for the requested "elevatedTerm" the
search results are as expected:
{noformat}
response: {
numFound: 5192,
start: 0,
maxScore: 1.9032197,
docs: [{
area: "press",
id: "core1docId1",
[elevated]: true,
[shard]: "localhost:9983/solr/core1"
}, {
area: "products",
id: "core2docId1",
[elevated]: true,
[shard]: "localhost:9983/solr/core2"
}, {
area: "press",
id: "core1docId2",
[elevated]: false,
[shard]: "localhost:9983/solr/core1"
},
...
{noformat}
(3) Remove the elevation entry for that "elevatedTerm" from one of the cores,
e.g. via comment
{code:xml}
core2:
<elevate>
...
<!--
<query text="elevatedTerm"><doc id="core2docId1" /></query>
-->
</elevate>
{code}
(4) Reload the modified core:
[http://localhost:9983/solr/admin/cores?action=RELOAD&core=core2]
(5) Request same query again and you get the NPE:
{noformat}
