Hi I create my index files and encode all numbers using solr's NumberUtils but searching not works!!! I created a custom query parser and override the getRangeQuery and getFieldQuery but no result will return. do I have to implement a custom analyzer too? currently I am using whitespace analayzer and I don't think it needs to be customized.
