Yes, sorry Just a typo.

Here's an example with the exampledocs that shows IN_STOCK_PRICE only if the item is in stock, and otherwise shows 0. This works because price is a single-valued indexed field that the fieldCache works on. http://localhost:8983/solr/query? q=*:* fl=id, inStock, IN_STOCK_PRICE:if(inStock,price,0) -Yonik http://lucidimagination.com
