Summary: issue with distance sorting on
SpatialRecursivePrefixTreeFieldType with spatialContextFactory JTS in Solr 9.9
/ 9.10
Key: SOLR-18016
URL: https://issues.apache.org/jira/browse/SOLR-18016
Project: Solr
Issue Type: Bug
Components: search
Affects Versions: 9.10, 9.9
Reporter: Umut Saribiyik
Attachments: image-2025-12-05-16-20-48-202.png
*Summary*
Sorting exception for {{SpatialRecursivePrefixTreeFieldType}} when using
{{spatialContextFactory="JTS". }}Identical to SOLR-18006 but for a different
field type.
*Description*
Hello [~janhoy] [~dsmiley]
an issue identical to *SOLR-18006* occurs when using the field type
*{{SpatialRecursivePrefixTreeFieldType}}* with
{{{}*spatialContextFactory="JTS"*{}}}.
Both sorting directions ({{{}asc{}}} and {{{}desc{}}}) result in the same
exception, which worked before solr 9.9 and 9.10
I was able to reproduce this on {*}main{*}, by extending the existing
{{TestSolr4Spatial2}} class with an additional test.
----
h2. *Steps to Reproduce*
h3. *1. Add JTS dependency*
Extend {{{}build.gradle{}}}:
{code:java}
implementation("org.locationtech.jts:jts-core:1.20.0") {code}
h3. *2. Disable dependency locking (for local testing only)*
In {{{}dependencies.gradle{}}}, comment out:
{code:java}
// lockAllConfigurations(){code}
(This is required only locally to avoid blocking the JTS dependency.){{{}{}}}
h3. *3. Extend schema with additional field type and field*
Add to {{{}schema-spatial.xml{}}}:
{code:java}
...
<fieldType name="location_jts" class="solr.SpatialRecursivePrefixTreeFieldType"
geo="true" maxDistErr="0.001" spatialContextFactory="JTS" distErrPct="0.025"
distanceUnits="kilometers"/>
...
<field name="location_jts" type="location_jts" uninvertible="true"
multiValued="false" indexed="true" stored="true"/>{code}
h3. *4. Add and run the test*
{code:java}
@Test
public void
test_geodist_on_SpatialRecursivePrefixTreeFieldType_with_jts_spatialContextFactory()
throws Exception {
String fieldName = "location_jts";

assertU(adoc("id", "jts-006", fieldName, "11.64,48.09"));
assertU(commit());

req(
"q", "*:*",
"fq", "{!geofilt}",
"sfield", fieldName,
"pt", "11.622015740056845,48.11308880280511",

"/response/docs/[3]/id=='jts-005'",
"/response/docs/[4]/id=='jts-001'",
"/response/docs/[5]/id=='jts-002'"); // closest
}{code}
