First off...I know enough about Solr to be VERY dangerous so please bare with me ;-) I am indexing the geonames database which only provides country codes. I can facet the codes but to the end user who may not know all 249 codes, it isn't really all that helpful. Therefore, I want to map the full country names to the country codes provided in the geonames db. http://download.geonames.org/export/dump/
<http://download.geonames.org/export/dump/>I used a simple split function to chop the 850 meg txt file in to manageable csv's that I can import in to Solr. Now that all 7 million + documents are in there, I want to change the country codes to the actual country names. I would of liked to have done it in the index but finding and replacing the strings in the csv seems to be working fine. After that I can just reindex the entire thing.
