: This index speeds up queries using the {{Mono|contains text}} keyword. Internally, BaseX handles two different index structures: the default index sorts all keys alphabetically by their character length. It is particularly fast if fuzzy searches are performed. The second index is a compressed trie structure, which needs slightly more memory, but is specialized on wildcard searches.
With {{Mark|Version 7.1}}, a new database option was introduced to support [[Options_(Snapshot)Options#UPDINDEX|incremental indexing]] of texts and attributes.
