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:

simptom
semptm
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?

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.

Do I need to download it, or it comes with the SOLR war? – Itay Moav -Malimovka Oct 04 '11 at 02:15
It comes with the SOLR war, but you need to configure it in your schema.xml. It's an analyser which analyse text during indexing and/or querying. – sbrattla Oct 04 '11 at 06:02
I have added this class to the config. But queries for "Symptom" are success, while queries for "Simptom" bring zero results. Do I have to add it somewhere to the query analyzer too? – Itay Moav -Malimovka Oct 04 '11 at 16:10
OK-FOUND IT, needed to add it to query analyzer AND index analyzer. Did the job :-) – Itay Moav -Malimovka Oct 04 '11 at 16:17
