Hoss Man updated SOLR-81:
-------------------------
Attachment: hoss.spell.patch
patch makes a few changes, if there are no objections i'll try to commit this
on monday....
* fixed NPE if no q param (when using cmd)
* fixed schema.xml to know about "words" field in spellchecker.xml
* cmd=rebuild needs to be disabled if termSourceField is null
* added "cmd=reopen" for people maintaining the spell index externally.
* added support for ramDir based spell index.
* can't do relative path to dataDir, because we can't getdataDir,
because SolrCore isn't done initializing yet.
* added more explanation to solrconfig.xml about meaning of params,
and changed the default values to work for anyone (using ramdir)
* I punted on the issue of field type encoding by making it clear in
the solrconfig.xml comments that termSourceField needs to use a simple
field type
Remaining issues...
* should we add a firstSearcher or newSearcher hook to rebuild in
the example solrconfig.xml ?
* i don't have an optinion about passing an IndexReader to
suggestSimilar, if we want to do that it shouldn't be a static reader,
it should come from the current request ... in the meantime i changed
the name of the current one to "nullReader" so it's clear what it is.
* the indenting is currently a hodgepodge of 2spaces vs 4 spaces ...
i'll fix after commiting (trying to keep the patch easy to read for now)
