* When indexing, for every post, for the location filter, | |
* Check to see if it has any location taxonomy set | |
* Check to see if selected location taxonomy has children (i.e. selected county has cities) | |
* Create a new index row for each child city | |
* | |
* So that Admin Panel editors can check only county for content | |
* But front-end users will be able to type city into autocomplete and find parent county content | |
