Erik Hatcher updated SOLR-7276:
-------------------------------
Attachment: SOLR-7276.patch
Here's a new patch that changes a few things:
* instead of local `expr` parameter for {!bool}, switched to `v` so that the
expression can work outside the curly brackets as `{!bool}<expression>`
* Added throwing of SolrException in createParser rather than returning null
when there's an error
* Trimmed a bunch of unnecessary stuff from the test solrconfig
> Add a Boolean Post Filter QParserPlugin

> This plugin enables existing post filter implementations to be combined using
> Boolean logic. It works by building a "parse tree" of referenced Post
> Filters. When a document is sent to the collect( ) method of the
> BooleanPostFilter, it is sent to all of the delegates that point to a local
> Collector that sets a flag if the DelegatingCollector calls its collect
> method. After all of the delegates have been polled, the parse tree output
> determines if the document should be ultimately collected.
> The syntax for the post filter is like this:
> {noformat}
> fq={!bool expr="(($foo OR $bar) NOT $baz)"}&foo={!foo ...}&bar={!bar ...
> }&baz={!baz ...}
> {noformat}
> Where "foo", "bar" and "baz" are all post filters.
