Adam Hiatt updated SOLR-81:
---------------------------

    Attachment: SOLR-81-spellchecker.patch

Good call on the DEFAULT_ACCURACY constant. BTW it should probably be .5.

As for:
> The SpellCheckerCommitRequestHandler assumes that:
>  a) one wants to populate the spellchecker index with data from another 
> Lucene index.
>  b) the Lucene index to be used for populating is available on the same box 
> where the spellchecker service is running. 

This does not necessarily have to be true (well a. sort of has to be true). The 
way I've been testing this is to make my primary index  an index of search 
terms + related metadata. The SpellChecker simply creates a separate index for 
the pieces it needs to do its work. In essence this is a standalone 
spellchecker. However, as you note, this same setup allows for the primary 
index to be any field. Can you see a downside to this approach?

> Use the simple approach of n-gramming outside of Solr and indexing n-gram 
> documents.  For example:
> <doc>
> <field name="word">lettuce</field>
> <field name="start3">let</field>
> <field name="gram3">let ett ttu tuc uce</field>
> <field name="end3">uce</field>
> <field name="start4">lett</field>
> <field name="gram4">lett ettu ttuc tuce</field>
> <field name="end4">tuce</field>
> </doc>
