ASF mail search - https://mail-search.apache.org/

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.

Standard search mode

The standard search mode uses "qt=dismax" mode, which is a very simplified syntax. The syntax is described here DisMaxQParserPlugin

Advanced search mode

Advanced mode (if enabled) allows searching by various different fields. To search for a specific field value use the following syntax:

fieldname:value

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.
