Turns out -XX:MaxRAM is crucial to run truly-micro jvm service in Docker. https://developers.redhat.com/blog/2017/04/04/openjdk-and-containers/ without it Docker just knock it outwith OutOfMemoryError (Docker's not JVM) The only understanding (speculation) I have so far is that a high load might trigger JIT that might consume additional memory far beyond the heap's -Xmx limit. Thanks to +Kristina Nedzvetskaya for resolving that bummer.

#Solr7.4 is out. On top of my head: `uniqueBlock()` in JSON Facet is a step torward block join facetig; the neat `"#tagging":{"syntax":"is introduced"}`. However, turns out it's still far from a smooth experience, WIP https://issues.apache.org/jira/browse/SOLR-12490. The coolest thing is +David Smiley's text tagger. Some time ago, I've build really cool query parser recognizing multi word entities from different fields. Perhaps something like this will be brought to Solr as well.

Introducing query parser in #Solr never got smoothly to me. In 7.3 {!filters} [1] as well as filters parameter [2] introduced for {!child} and {!parent} has a caching bug [3] spotted by +David Smiley. Thanks! It'll be fixed in 7.4
Overall idea is to bring tagging/exclusion trick [4] for multivalue facets to other places like JSON Facet API and parent-child faceting.

so true, so touching.
Users' ability to get relevant product lists is highly dependent on their ability combine filtering values — yet 32% of e-commerce sites don’t allow this. See our latest usability test findings on using an ‘OR’ logic for filter values: https://baymard.com/blog/allow-applying-of-multiple-filter-values
