I would like to make it easier to search in a field that we cannot index or store in non-hashed or encrypted form. Is there any way to tell solr about the hash (or encrypt) speicfic field before comparing with the index?
In short, I don’t think it’s easy, and it depends on what level of security you need.
As a general simple solution, you can save the entire index in an encrypted file system, for example. eCryptfs or TrueCrypt (see the difference between block encryption and fs-level encryption )
