General Overview

As of 3.1.2-GA of PriceList, there is now the capability to use nested Solr documents for pricing. This allows for client's
utilizing sales or contract price lists to properly facet, filter and sort by price when considering multiple price lists
on the context. Now when considering multiple contract price lists at once, the lowest price will be the one that is used
for facet counts, for sorting by price, and when filtering to a range of prices.

To enable this functionality is very simple. All that needs to be done is to set the property blPriceLists.use.nested.pricing
to true, and then trigger a re-build of your Solr index. As always be sure to test this outside of production the first
time you use it to be sure everything gets indexed correctly. Existing modifications to the way prices are searched and indexed
will likely conflict with this new functionality; if this is your case, reach out and we can help facilitate an upgrade.
