Book Descriptions:
Elasticsearch ist ein auf Apache Lucene basierender Suchserver, der JSON-Dokumente speichern und durchsuchen kann. Durch den verteilten Aufbau ist die Ablage sehr großer Datenmengen möglich. Neben Volltextinhalten können auch strukturierte Daten verwaltet und mit Aggregationen leicht gruppiert und ausgelesen werden. Dokumente, Suchanfragen und administrative Aufgaben werden in JSON formuliert und per HTTP oder über die Java-API ausgetauscht.

Das Buch stellt anhand eines durchgehenden Beispiels die Nutzung von Elasticsearch vor. Nach einem einführenden Kapitel, in dem eine klassische Suchanwendung von Grund auf aufgebaut wird, werden in den anschließenden Kapiteln jeweils unterschiedliche Aspekte genauer beleuchtet. Unter anderem werden die folgenden Themenbereiche angesprochen:

• Umgang mit Text
• Relevanz in Suchergebnissen
• Möglichkeiten der Indizierung
• Verteilung der Daten
• Datenmodellierung
• Aggregationen
• Aspekte des Produktivbetriebs
• Logdaten in Elasticsearch

Der Großteil des Buches ist unabhängig von der Programmiersprache gehalten, es wird jedoch auch auf die Java- und JavaScript-APIs zum Zugriff auf Elasticsearch eingegangen.

Der Leser hat nach der Lektüre das notwendige Rüstzeug, um eigene Anwendungen auf Basis von Elasticsearch umzusetzen.
