Cassandra Targett commented on SOLR-9510: ----------------------------------------- [~mkhludnev], I took a look at the patch and changed a couple of things. First, I changed the sections you had titled "Often Mistake" to be CAUTION blocks instead - this separates them from the main text in a better way. I noticed that both these sections mention what the error was in older versions...how long ago was that? If it was more than a couple of releases, let's remove those. The second thing I changed was to make the {{[literal]}} blocks that included query examples into {{[source,text]}} blocks - I did this for consistency. If we ever decide to change how those blocks look in either HTML or PDF, these won't be odd men out as it were. I left the other literal blocks that showed the error since that's probably fine. When I applied the patch, Git complained about trailing white space, so I found around about 5 or so on the entire page (not only the section you're working with) and I fixed all of them. So my patch has some really minor changes for the page as a whole that aren't related to your changes - just didn't want you to get confused. +1 from me, thanks. If you can commit it to 7.3 before the RC gets made (waiting on binaries), then it will be in the 7.3 Ref Guide. > child level facet exclusions > ---------------------------- > > Key: SOLR-9510 > URL: https://issues.apache.org/jira/browse/SOLR-9510 > Project: Solr > Issue Type: Improvement > Security Level: Public(Default Security Level.

Challenge > * Since SOLR-5743 achieved block join child level facets with counts roll-up > to parents, there is a demand for filter exclusions. > h2. Context > * Then, it's worth to consider JSON Facets as an engine for this > functionality rather than support a separate component. > * During a discussion in SOLR-8998 a solution for block join with child > level exclusion has been found. > h2. Proposal > It's proposed to provide a bit of syntax sugar to make it user friendly, > believe it or not. > h2. List of improvements > * introducing a local parameter {{filters}} for {{{!parent}} query parser > referring to _multiple_ filters queries via parameter name: {{{!parent > filters=$child.fq ..}..&child.fq=color:Red&child.fq=size:XL}} > these _filters_ are intersected with a child query supplied as a subordinate > clause. > * introducing \{{{!filters param=$child.fq excludeTags=color > v=$subq}&subq=text:word&child.fq= \{!tag=color}color:Red&child.fq=size:XL}} > it intersects a subordinate clause (here it's {{subq}} param, and the trick > is to refer to the same query from {{{!parent}}}), with multiple filters > supplied via parameter name {{param=$child.fq}}, it also supports > {{excludeTags}}. > h2. Notes > Regarding the latter parser, the alternative approach might be to move into > {{domain:{..}}} instruction of json facet. From the implementation > perspective, it's desired to optimize with bitset processing, however I > suppose it's might be deferred until some initial level of maturity. > h2.
