Hyphenation in Query Boost Function
-----------------------------------

                 Key: SOLR-1172
                 URL: https://issues.apache.org/jira/browse/SOLR-1172
             Project: Solr
          Issue Type: Bug
          Components: search
    Affects Versions: 1.3
         Environment: Windows, PC
            Reporter: Yao Ge


I have a field named "last-modified" that I like to use in bf (Boot
Functions) parameter: {{recip(rord(last-modified),1,1000,1000) }} in DisMaxRequestHander.
However the Solr query parser complain about the syntax of the formula.
