Elasticsearch

Lucene search over an index with a field explorer, three result layouts, a time-range filter and a live tail.

Elasticsearch in Kubo
A query_string search with chosen fields as columns, bounded by a relative time range.

An Elasticsearch cluster is a top-level connection — a URL plus either an API key or Basic auth, with an optional CA — and it opens as a single Search view.

There is deliberately no separate “indices” tab. The index is chosen from a searchable picker modal that shows health, document count and size per index (from _cat/indices) and can hide system indices, with those same stats repeated inline under the field once one is selected. An index list is something you use to search, not a destination.

Everything else — the query language, the columns, the layouts, the tail — is covered in the pages below. If you also run OpenObserve, the two log screens are built to the same brief on purpose, so what you learn on one transfers.
