Hoss Man reopened LUCENE-2604:
------------------------------
Re-opening ... some issues were pointed out in a recent mailing list thread
that definitely seem like they should be addressed before this is officially
released...
* queryparsersyntax.xml doesn't mention this feature at all -- as major new
syntax is should really get it's own section with an example showing the syntax
* queryparsersyntax.xml's section on "Escaping Special Characters" needs to
mention that '/' is a special character
* QueryParser.escape needs to include '/' in the characters it escapes
** ditto for Solr's ClientUtils.escapeQueryChars and
SolrPluginUtils.partialEscape
** i've got a patch for this i'll commit as soon as the tests finish.
Also: Given that Yury encountered some real world situations in which the new
syntax caused problems with existing queries, it seems like we should
definitely make a note about this possibility more promonient ... i'm not sure
if it makes sense in MIGRATE.txt but at a minimum it seems like the existing
CHANGES.txt entry should mention it, maybe something like...
{noformat}
* LUCENE-2604: Added RegexpQuery support to QueryParser. Regular expressions
are now directly supported by the standard queryparser using the syntax...
fieldName:/expression/ OR /expression against default field/
Users who wish to search for literal "/" characters are advised to
backslash-escape or quote those characters as needed.
