Luke P Warwick commented on SOLR-9665:
--------------------------------------
another example: We have a facet who's values go from the 70's to the 120s
(width of skis). The values end up looking like this:
Brake Width (mm)
100 (7)
110 (9)
115 (6)
120 (3)
74 (2)
80 (1)
85 (1)
90 (9)
93 (1)
95 (1)
Facets like this EnumField doesn't work well on since the values aren't always
static and EnumField requires that.

> Key: SOLR-9665
> URL: https://issues.apache.org/jira/browse/SOLR-9665
> Project: Solr
> Issue Type: New Feature
> Security Level: Public(Default Security Level. Issues are Public)
> Components: faceting
> Reporter: Luke P Warwick
>
> As a person, I need facet values to be in predictable, intuitive spots so
> that I can quickly and easily find the values that are appropriate to me.
> Problem Statement: Today Solr has two default facet sort orders, neither of
> which provides predictable, intuitive facet value orders for people when the
> values start with numbers.
> Goal: Address the problem where index sorts facet values how a computer would
> rather than how a human would. This is very problematic for E-commerce
> facets like 'size' and 'tire width'
> Acceptance Criteria:
> 1. Sorts facet values numerically from lowest to highest
> 2. Works with both numeric and string fields (thus working on values that
> include letters... 25 mm, 30 waist, 32 Waist, 4 Petite)
> 3. If facet values don't start with a number, they are sorted alphabetically,
> after all values that do start with a number
> 4. If facet values are equal numerically, sort the numerically equal values
> alphabetically. Example: 10,10 Petite,10 Tall,12, Petite, 12 Tall
> 5. Integers and Floats are supported (even if string field)
> Examples:
> Women's Pants Sizes:
> 8
> 8 Tall
> 10
> 10 Petite
> 10 Tall
> 12
> 12 Tall
> 14 Petite
> 26 Waist
> 28 Waist
> 30 Waist
> One Size
> Bike Wheel Sizes:
> 20 Inches
> 24 Inches
> 26 Inches
> 27 Inches
> 27.5 Inches
> 27.5+ Inches
> 29 Inches
> 650c
> 700c
