Otis Gospodnetic commented on SOLR-572:
---------------------------------------
I'm still confused with some of the names in that config.
indexDir looks like the path to the spellchecker index. But there is also
spellcheckInexDir. Is there a functonal difference?
Regarding the "wouldn't it also be good to be able to read field values from a
vanilla Lucene index?" - the use case is that not all source indices should
have to be Solr indices. What if I have a vanilla Lucene index on the machine
and I want the SCRH to build a SC index from that index's "title" field? That
is, I want the functionality of SCRH, but I don't have my Lucene index under
Solr. Is that doable?

> Expose the Lucene contrib SpellChecker as a Search Component. Provide the
> following features:
> * Allow creating a spell index on a given field and make it possible to have
> multiple spell indices -- one for each field
> * Give suggestions on a per-field basis
> * Given a multi-word query, give only one consistent suggestion
> * Process the query with the same analyzer specified for the source field and
> process each token separately
> * Allow the user to specify minimum length for a token (optional)
> Consistency criteria for a multi-word query can consist of the following:
> * Preserve the correct words in the original query as it is
> * Never give duplicate words in a suggestion
