< p > Full-text search allows all messages to be indexed, so that mail clients can quickly and efficiently search messages by their full text content. Dovecot supports a variety of community supported < a href = "https://doc.dovecot.org/configuration_manual/fts/" > FTS indexing backends< / a > .< / p >
< p > Docker-mailserver comes pre-installed with two plugins that can be enabled with a dovecot config file.< / p >
< p > Please be aware that indexing consumes memory and takes up additional disk space.< / p >
< h3 id = "xapian" > < a class = "toclink" href = "#xapian" > Xapian< / a > < / h3 >
< p > The < a href = "https://github.com/grosjo/fts-xapian" > dovecot-fts-xapian< / a > plugin makes use of < a href = "https://xapian.org/" > Xapian< / a > . Xapian enables embedding an FTS engine without the need for additional backends.< / p >
< p > The indexes will be stored as a subfolder named < code > xapian-indexes< / code > inside your < code > mail< / code > folder. With the default settings, 10GB of email data may generate around 4GB of indexed data.< / p >
< p > While indexing is memory intensive, you can configure the plugin to limit the amount of memory consumed by the index workers. With Xapian being small and fast, this plugin is a good choice for low memory environments (2GB) as compared to Solr.< / p >
