is it possible to do a case insensitive search on an exact lucene index (auto index)? Marko asked this same question some time ago http://www.mail-archive.com/us...@lists.neo4j.org/msg07954.html

in the doc i found this
http://docs.neo4j.org/chunked/milestone/indexing-create-advanced.html

and the to_lower_case parameter seems to only work for fulltext and not exact indexes.
i tried the following:
stop service
delete index
start service
POST /db/data/index/node/ {"name":"node_auto_index", "config":{"type":"exact","to_lower_case":"true","provider":"lucene"}}
re-index all nodes

but the index is still case sensitive (not all lower case)

is there a lucene trick to solve this (i searched and could not find one but i am not a lucene expert).
or can you add a setting that will lowercase all auto indexed values and searches such as auto_index_lowercase=true

Hi there,
I don't think you can provide custom config to an autoindex. That
would be a nice feature to add, could you raise an issue? The
autoindex is thought to be not modifiable by the user because it is -
an autoindex. However, configuration could be more flexible, granted.

Cheers,
