Note: only mails from private mailing list archives are indexed. Unless you are a Member or PMC member, this won't do you any good.
To search mails from our many public archives (e.g. all user and developer lists and more) please use a third party mail search engine.
The Mail Search engine uses Apache Lucene and Apache Solr.
The standard search mode uses "qt=dismax" mode, which is a very simplified syntax. The syntax is described here DisMaxQParserPlugin
Advanced mode (if enabled) allows searching by various different fields. To search for a specific field value use the following syntax:
Search terms can be combined. The default operator is AND. Use a leading "-" sign to reject results containing the term. The wildcard meta-character is "*". Use double-quotes to embed spaces in values.
The searchable database includes the following fields:
Note that the project-listname values are displayed at the top left of each result.
