Excerpt

Facets offer a range of customizations when setting them up. This page describes how to configure and manage facets using the squirro user interface.

If facets are managed by the squirro dataloader, consult the dataloader configuration documentation here

...

There are a number of ways to create facets in a project:

  • From data: the easiest way is to simply specify a facet value when uploading data.
  • Enrichments: similar to loading from data, enrichments can just set a facet value where needed.
  • Manually: a facet can be configured up-front, before loading data. This is mandatory for more complex facets.

...

Note

The following names are reserved names and cannot be used for facets:

  • author: reserved for the item author field
  • is: reserved for state fields (read/starred)
  • language: reserved for the item language field
  • provider: reserved for the item provider field
  • smartfilter: reserved by query language for smartfilters
  • sort: reserved by query language for sorting
  • source: reserved for the item source field
  • time_increment: reserved by query language for histogram time bucketing


Note

Facet names cannot contain the $-sign.


Note

Facets Cannot be removed from a project once created. Additionally, the name and type of the facet cannot be changed.

...

  • To format facet values containing dates (and times), Squirro offers three formatting options, defined in the Facets configuration screen.
  • Each option is accompanied with a preview of the resulting formatted value.

The separate page Format Strings documents this Moment datetime format string.
