title: Solr - change default facet order for front-end
body: <p>I"m very new to Solr so pls forgive my ignorance if this question is too simplistic. i'm having issue where the facets are working fine but due to nature of the products the default order of Numeric-Alpha isn't ideal. Scenario: site is for jewlelry and Rings come in numeric sizes 5, 6,7 etc and S, M, L, XL. The problem is with the alphas -- i want it to be is size order not alpha so right now XS is appearing at end but I want it to appear before S. XL is above XS but I want XS to be first and XL to be last etc. Make sense? Any ideas on how to customize and make it the desired size order? </p>
  
  <p>Current: 5,6,7,8, M, L, One Size, S, XL, XS
  Desired: 5, 6,7, 8, XS, S, M, L, XL, One Size</p>
