Guillaume Smet updated LUCENE-7044:
-----------------------------------
Description:
Hi,
Context: https://hibernate.atlassian.net/browse/HSEARCH-1927
By using {{SortedNumericDocValuesField}}, we can index several numeric values
for the same field.
But we can't execute a range query on it using {{LongRangeFacetCounts}}.
Lucene fails with the following stacktrace:
{code}
java.lang.IllegalStateException: unexpected docvalues type SORTED_NUMERIC for
field 'ingredients.price' (expected=NUMERIC). Use UninvertingReader or index
with docvalues.
at org.apache.lucene.index.DocValues.checkField(DocValues.java:208)
at org.apache.lucene.index.DocValues.getNumeric(DocValues.java:227)
at
org.apache.lucene.queries.function.valuesource.LongFieldSource.getValues(LongFieldSource.java:67)
at
org.apache.lucene.facet.range.LongRangeFacetCounts.count(LongRangeFacetCounts.java:80)
at
org.apache.lucene.facet.range.LongRangeFacetCounts.<init>(LongRangeFacetCounts.java:69)
{code}
Either {{LongRangeFacetCounts}} needs some tweaking to accept
{{SORTED_NUMERIC}} or we need another implementation to deal with
{{SortedNumericDocValuesField}} (and probably an implementation of both for
Doubles).
