My xml has an element that looks like this: <post_date>20130218</post_date>.
So I made a custom date format yyyyMMdd. This worked fine for this element/field/facet. But then ICA's built-in date appeared as garbage. My guess is that the built-in date had 8 digits or more, and so it could be parsed as yyyyMMdd.
Can I apply the custom date format only to post_date?
Alternatively, can I use a field filter to insert dashes so that my post_date appears as 2013-02-18, which ICA does support?
Any other ways to handle yyyyMMdd?
