What will you learn

  • Introduction to basic ES concepts
  • Document APIs
    • Single document APIs
      • Index API
      • Get API
      • Delete API
      • Update API
    • Multi-document APIs
      • Multi Get API
      • Bulk API
      • Delete By Query API
      • Reindex API
  • Mapping

Mapping is the process of defining how a document, and the fields it contains, are stored and indexed. For instance, use mappings to define:

  • which string fields should be treated as full text fields.
  • which fields contain numbers, dates.
  • whether the values of all fields in the document should be indexed into the catch-all _allfield.
  • the format of date values.
  • custom rules to control the mapping for dynamically added fields.
  • Term level queries
    • terms query. Find documents which contain any of the exact terms specified in the field specified.
    • range query. Find documents where the field specified contains values (dates, numbers, or strings) in the range specified.
    • exists query. Find documents where the field specified contains any non-null value.
    • wildcard query. Find documents where the field specified contains terms which match the pattern specified, where the pattern supports single character wildcards (?) and multi-character wildcards (*)
    • regexp query. Find documents where the field specified contains terms which match the regular expression specified.
    • ids query. Find documents with the specified type and IDs.
  • Specialized queries
    • script query. This query allows a script to act as a filter. Also see the function_score query.
    • percolate query. This query finds queries that are stored as documents that match with the specified document.
  • Aggregations
    • Bucketing. A family of aggregations that build buckets, where each bucket is associated with a key and a document criterion. When the aggregation is executed, all the buckets criteria are evaluated on every document in the context and when a criterion matches, the document is considered to “fall in” the relevant bucket. By the end of the aggregation process, we’ll end up with a list of buckets – each one with a set of documents that “belong” to it.
    • Metric. Aggregations that keep track and compute metrics over a set of documents.
    • Pipeline. Aggregations that aggregate the output of other aggregations and their associated metrics
