Multi-map / Reduce indexes with IndexDefinitionBuilder

[toochevere]

I am using IndexDefinitionBuilder (C# client) to create indexes. The indexes are being created in a library and the expressions that form the basis of the indexes will vary according to the use of the library.

Up until now these have only been map or single map / reduce indexes. Recently a use case came up where a multi-map / reduce index would be a very clean solution to the particular problem. However IndexDefinitionBuilder only takes one map expression.

How can build a multi-map reduce index with IndexDefinitionBuilder or something similar? A workaround I can see is to dynamically compile a class that uses AbstractMultiMapIndexCreationTask which feels very heavy-handed, but it would let me stay in pure C#. Any better ideas would be welcome.

Hi

Yes, using the IndexDefinitionBuilder is supported for single map or map-reduce index for now. Using AbstractMultiMapIndexCreationTask for creation of multi map index is the correct way.
