The code in the repository was the basis for site-wide search on the ShareNet
project and I recently talked to the guy who was the lead developer on this
and his comment was: "To save time you better start from scratch".
Here's the bit that I experienced (I worked on it as well):
* Its performance with real-life amount of data was simply awful.
* It didn't work with umlauts.
* It has a lot of weird, weird code like if's that are always true, dynamic
ddl, abstraction layers etc.
Given that no-one has worked on it for more than two years it should be even
more useless to use it. E.g. it still indexes the forums packages which has
been deprecated a long time ago.
The ACES solution is the ACS3 solution which has worked in this way or another
on many ACS-backed sites, I worked about two years with it and I find it
pretty reasonable, so I think it is sound approach to port it.
