Term stat facets on multiple fields

Elastic Stack Elasticsearch
1

Hi All,

Using Terms Stats Facet we can create sums, counts and averages etc. of a
value given in one field, aggregated by all values of another field. It's a
way of creating statistical cross-tabs.

Does this feature work on more than one aggregation field? In other words,
if I had a data set of: Building type, year built, area. I want to apply
term stat facets on Year and area.

If my data looks like (this is just sample data):

*BuildingType Year area *
Residential 2004 3500
Residential 2005 3600
Residential 2006 3700
Residential 2007 3800
Residential 2008 3700
Residential 2009 3650
Commerical 2004 14,000
Commercial 2005 15,000

Then i want output as:

Residential min(Year)=2004, max(year)= 2009, min(area)=3500,
max(area)=3800
Commerical min(Year)=2004, max(year)= 2004, min(area)=14000,
max(area)=15000

To apply term stat facet on single column (lets say "area") my query is:

TermsFacetBuilder termsFacetBuilder = FacetBuilders.termsFacet("facet1");
termsFacetBuilder.keyField("BuildingType").valueField("area");

SearchRequestBuilder srb
=client.prepareSearch("TweetIndex").setQuery(qb).setSearchType(SearchType.QUERY_THEN_FETCH).addFacet(termsFacetBuilder);

searchResponse = srb.execute().actionGet();

In search response i am able to get my result if apply facet on single
column.

Could I somehow apply term stat facets on two fields?

You can do this with1.0beta2 that was just released using the new
aggregations functionality. You would create a terms aggregator on
building type and then nest a min and max aggregator for year and area.

Hi Matt,

Thanks for response !!

I am using elasticsearch-0.90.5.

One way is that apply 2 facets separately and merge the result in-memory
and then i can return the result. But its costly operation.

Is there any other way possible to do this or i'll have to upgrade
Elasticsearch to get this functionality?
