Combining several fields for facets.
Hi!
How can I create a facet combining 2 (or more) different fields, without
using copy field to union them?
For example if I have this documents:
Doc1 with the field X contains the value a and field Y contains the value b
Doc2 with the field X contains the value c and field Y contains the value a
Doc3 with the field X contains the value d and field Y contains the value d
I want to get this facet:
XY
a 2
b 1
c 1
d 1

How many different values do you have in your fields and do you know them ?
Faceting by query is not an option for you ?

Using a copy field will require reindeer of my data, I am looking for a
solution without reindex.

Why not copy them into a facet field. Space constraints?
If space is the concern, you need to remember that facets use indexed
value, so that copy target field has absolutely no reason to be
stored. And indexed values are stored only once per unique token, so
then you are only paying for posting table, which is what you need
anyway to do the counts.

Alex.

If you used pivot facets you'd get all the information back, but you'd have
to combine the cells yourself.
Best,
