Erik Hatcher commented on SOLR-7276:
------------------------------------
Another question - should we stick with $dollar-sign-prefixed values in the
expressions? It's dangerously close to the macro substitution feature that
uses ${curly-bracket-reference}. In these expressions the only non-operator
tokens will be parameter references, right? So maybe an expression could
simply be `fq={!bool}(foo OR bar) NOT baz` without dollar-signs?

> 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.
