cql-ruby provides a common querly language (CQL) parser. CQL is a format frequently used in the library world. This parser was translated from the CQL-Java parser written by Mike Taylor available here http://zing.z3950.org/cql/java/
The parser builds a CQL parse tree suitable to serializing to various forms, built in are to_cql, to_xcql and to_solr (build a solr-lucene search query from cql)
sudo gem install cql_ruby
