SOLR : Matching Street Types

I am doing address matching in SOLR and for most part it is working fine. I have a situation where I would like return the same value for the following two cases:

10 SMITH COURT REDBANK PLAINS QLD
10 SMITH CT REDBANK PLAINS QLD

The street type abbreviation CT = COURT.

One option I have tried is to have both the records in SOLR, but that just leads to duplication of a lot of data. I have ~30 million records, but these could be halved if there is a way in SOLR to match as explained above.

Any suggestions how to handle this issue?
