Dawid Weiss commented on SOLR-2378:
-----------------------------------
We could... after all when 4.0 sees the light of day backwards compatibility
does not need to be (strictly) enforced, right? I would love somebody who
actually uses this piece of functionality to test it in a realistic setting
first though. If nothing else, this would at least tell us if any performance
gain is visible at all (I'm guessing the HTTP stack will be the bottleneck
before we can see any differences between all the implemented methods). The big
drop in RAM usage should be visible right away, so this is a bonus.

> Implement a subclass of Lookup based on finite state automata/ transducers
> (Lucene FST package). This issue is for implementing a relatively basic
> prefix matcher, we will handle infixes and other types of input matches
> gradually. Impl. phases:
> - -write a DFA based suggester effectively identical to ternary tree based
> solution right now,-
> - -baseline benchmark against tern. tree (memory consumption, rebuilding
> speed, indexing speed; reuse Andrzej's benchmark code)-
> - -modify DFA to encode term weights directly in the automaton (optimize for
> onlyMostPopular case)-
> - -benchmark again-
> - -benchmark again-
> - -modify the tutorial on the wiki- [http://wiki.apache.org/solr/Suggester]
