Mark Harwood commented on LUCENE-2454:
--------------------------------------
bq. Looking at the structure of the BooleanQuery, I would expect this to work
correctly.
I've found it to be robust so far - you just need to be clear about directing
criteria at only one child or potentially different children.
The main challenge in using this functionality is allowing users to articulate
the nuances of such queries and Lucene-3133 is a holding place for this.
Under the covers using the same cached filter for parent filters certainly
helps with performance and I typically wrap the ParentFilter tag in the XML
queries with a <CachedFilter> tag to achieve this
