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

You have been asked to provide SRU access to your website, so that the dynamic and exciting library community can find and promote access to and awareness of your rich content. You discover that in order to support SRU, dang! you need a CQL parser. Well now you have one.

require 'cql_ruby' parser = CqlRuby::CqlParser.new puts parser.parse( 'dog and cat' ).to_solr
