Facet by entire field text

Elastic Stack Elasticsearch
1

Hello,

Can one have a facet that is field based? The field is analyzed, but I
dont want a terms facet. I would like to facet on the entire text of the
field?

Thanks

You would need to set the field as multi-field, with one field set as
non_analyzed (or use the keyword analyzer). You can then use the term facet
on this new field.

This change requires a re-index. Your current index does not have the
proper tokens to create the facet you are looking for.

Iva,

Thanks. So being new to Elasticsearch a few additional questions?

  1. Setting field as multi-field is via a mapping, correct?
  2. How does one re-index? My understanding was it cant be done?

Correct. Multi-field's main use case is exactly what you are looking for.
Same field: one field analyzed, the other not.

  1. How does one re-index? My understanding was it cant be done?

Indexing is application dependent, so you would need to kick off
whichever mechanism you have in place. I believe there is a reindexing
plugin. Not sure, never used it.

Technically, you do not need to reindex, but only newer documents will have
the mapping and contain both fields. When you have a facet over the new
field, the older documents will not appear.
