Re: regex constructs allowed in queries

Yeah, upon re-reading the grammar, you're quite right. backslash escapes are legal, but there doesn't look like there's any concept of a predefined character class. For whatever reason, it looks to me like Lucene is just implementing its own regex matching—which may make complete sense for reaso

Re: regex constructs allowed in queries

Thanks for the full details -- being able to see exactly how the queries are recieved & parsed is important for rulling out simple things like client side escaping (or lack of) and server side metacharacter handling in the query parser. : Some things work the way I'd expect, some clearly don't

Re: regex constructs allowed in queries

The context for this is that I'm migrating an application from Solr 3.5 to 4.4. We had regex search working (in kind of a hacky way), but since 4.x has regex search support built in, I'm trying to switch to that. Some things work the way I'd expect, some clearly don't. So my question was, in the

require a THIRD level of escaping (four backslashes for each backslash to be used in a regex), such as if you were using SolrJ. -- Jack Krupansky -Original Message- From: Hugh Cayless Sent: Thursday, August 29, 2013 12:49 PM To: solr-user@lucene.apache.org Subject: Re: regex constructs

Re: regex constructs allowed in queries

You probably just need to escape the backslashes with a backslash - otherwise the query parser will treat your backslashes as escapes and remove them. This is not unlike placing a regex in a Java string literal. -- Jack Krupansky -Original Message- From: Hugh Cayless Sent: Thursday,
