Subject [jira] Created: (LUCENE-1122) queryparser whitespace escaping and documentation?
Date Tue, 08 Jan 2008 08:55:33 GMT
queryparser whitespace escaping and documentation?

                 Key: LUCENE-1122
             Project: Lucene - Java
          Issue Type: Improvement
          Components: QueryParser, Website
            Reporter: Hoss Man

as noted in this solr thread...'s possible to escape a whitespace character in the value of a term or prefix query by
using a backslash so that the QueryParser will not treat it as "special" (ie: won't split
on it when dividing the input into chunks for analysis).

at a minimum, this should be noted here...

...but it got me wondering...

   * is this a side effect of something else, or will QueryParser really respect this everywhere?
even in field names? (i haven't tested) ... i think this is a result of QueryParser allowing
you to escape any character even if it isn't "special" to the syntax
   * shouldn't a space be considered "special" since it does trigger certain behavior? ...
so shouldn't QueryParser.escape(String) escape spaces as well as the other special characters?
