Andrzej Bialecki commented on SOLR-2378:
-----------------------------------------
bq. I see TSTLookup and JaspellLookup (Andrzej, will you confirm, please?)
sorts matches in a priority queue by their associated value (frequency I guess)
Correct. I agree that the name is so-so, I inherited it from the spellchecker
API - feel free to change it.
bq. the Dictionary can come from various sources, ...
Yes. This is again a legacy of the Lucene SpellChecker API. I tried to extend
this API in Solr without changing it in Lucene (see the *IteratorWrapper
classes and TermFreqIterator) but ultimately it would be better to refactor
this.
> FST-based Lookup (suggestions) for prefix matches.
