how do I make SOLR find mistakes?

Question

I am looking for all document with "symptoms" in them.
I want the same or close results also for the following:

1. simptom
2. semptm
3. sympt

etc.
This is just an example to what I mean, I do not need a solution just for this specific word..
How do I define this in SOLR config files?

Answer 1

I haven't tried it myself, but it might be that the PhoneticFilterFactory can be of help. It generates phonetically similar tokens based on a provided token.
