NICE!, now my hopes are gone!.
so I guess I must make use de facto lucene framework. and follow the examples in LIA?
ok.. what can one do... :(
thx

Be aware that ERIndexing is only an experiment (and was write-only code, I don't use it yet). In particular it has several severe drawbacks:
- it doesn't really handle multiple instances (possibly) or servers (definitely). That means, for the cases where you actually *do* need the speed of lucene, ie. high-traffic, high-volume which means many servers, you can't use it as is. At least the auto-indexing won't work without some central notification point that actually does the indexing and then redistribute the indexes.
If you don't account for that, your indexes won't really match your DB, which means that you will find the wrong stuff super-fast...
I don't have a good solution to this, maybe someone who actually uses it might.
- The DB store for the indexes was an experiment to fix at least the redistribution problem, but this was truly write only, so use at your own risk.
- it duplicates your DB indexes and depending on your DB type and query, your query to resolve the faults probably won't be that much faster than a normal query would have been.
- it should really be an EO adaptor instead, which would mean that you could use it in a simple displayGroup. But then again, one of the main points in Lucene is that you don't really need a strict schema to work with it - although you'll probably have one.
