Review: Critical Bug — Field name mismatch will break expression search

The ES mapping and SearchHelper are renamed to anatomicalExpressionSlim, but the Java model classes that produce the indexed documents still use the old name anatomicalExpression:

• SearchableItemDocument.java:50 — field is still Set<String> anatomicalExpression
• IndexerCache.java:52 — cache map is still Map<String, Set<String>> anatomicalExpression
• IndexerCache.java:155 — document.setAnatomicalExpression(...) still uses the old setter

Since these classes use Lombok @Getter/@Setter with no @JsonProperty annotation, Jackson will serialize the field as "anatomicalExpression" in ES documents. But the mapping now defines the field as "anatomicalExpressionSlim", and search queries/facets/highlights all reference "anatomicalExpressionSlim".

Result: After reindexing, anatomical expression data will be indexed under the old unmapped field name, while all search/facet/highlight logic looks for the new name. Expression facets and search hits for anatomical terms will return empty.

Fix: Rename the field in SearchableItemDocument and IndexerCache to anatomicalExpressionSlim (or add @JsonProperty("anatomicalExpressionSlim") annotations). The two Groovy test files that reference anatomicalExpression should also be updated:

• GeneDocumentIntegrationSpec.groovy:79
• CategoriesAndFieldsIntegrationForLaterSpec.groovy:54
