> 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.
