Hey,
I have indexed "author","module_id" fields as
SortedSetDocValuesFacetField and "time", "price","salary" fields as
NumericDocValuesField.
My Category looks like:
*module_id
-> author
*price
module_id and price are parent categories. After selecting any one of the
facets from module_id, sub-category ie "author" field will be shown.
*Use-case:*
1. I have received path values from user as "module_id:1" and "price:100 TO
500" and also need to perform drillsideways search.
*initializing drilldown query*
DrillDownQuery drillDownQuery = new DrillDownQuery(facetsConfig,
> userGivenSearchQuery);
> drillDownQuery.add("module_id","1");
> drillDownQuery.add("price",NumericRangeQuery.newDoubleRange("price",
> 100.0, 200.0, range.minInclusive, range.maxInclusive));

* hits and facets computation*

java.lang.IllegalArgumentException: dimension "price" was not indexed

Am I did anything wrong???
Kindly post your suggestions.
Thanks,
