Lucene library

Hi all. I recall hearing about there being a PHP port of the Lucene library some years ago, but I don't recall whence it came. It was a stand-alone PHP lib, which needed some integration to be viable as an actual search engine but worked up to a point by storing data straight on disk as files. That meant it didn't scale beyond a few tens of thousands of records, but that's still a decent number. Does that ring a bell for anyone? Anyone know if it still exists, and if so where? I didn't find it in https://packagist.org/ , which is where I figured it would be if it were still maintained. I may have a use for it if it still exists. --Larry Garfield
