![]() Switching from a text field to a keyword field For an in-depth comparison and decision flowchart, see Otherwise, use the keyword field type for faster searches, faster indexing,Īnd lower storage costs. You plan to regularly search the field using any wildcard pattern. The field contains values larger than 32KB. You plan to regularly search the field using a pattern with leading wildcards, The field contains more than a million unique values. Defaults to false.ĭimension fields have the following constraints: Marks the field as a time series dimension. Elastic will apply best effort to fix any issues, but features in technical preview are not subject to the support SLA of official GA features. This functionality is in technical preview and may be changed or removed in a future release. Whether full text queries should split the input on whitespace How to pre-process the keyword prior to indexing. Which scoring algorithm or similarity should be used. Whether the field value should be stored and retrievable separately from Script are normalized as usual, and will be ignored if they are longer ![]() The document will be rejected with an error. If a value is set for this field on the input document, then If this parameter is set, then the field will index values generatedīy this script, rather than reading the values directly from the ![]() This parameter can only be set if the script field is Will register the field in the document’s Will cause the entire document to be rejected, and continue, which Note that this cannot be set if the script value is used.ĭefines what to do if the script defined by the script parameter Defaults to null, which means the field is treated as missing. Whether field-length should be taken into account when scoring queries.Īccepts a string value which is substituted for any explicit null What information should be stored in the index, for scoring purposes.ĭefaults to docs but can also be set to freqs to take term frequency into account keyword fields that only have doc_valuesĮnabled can still be queried, albeit slower. Should the field be quickly searchable? Accepts true (default) andįalse. Please however note that defaultĭynamic mapping rules create a sub keyword field that overrides this Multi-fields allow the same string value to be indexed in multiple ways forĭifferent purposes, such as one field for search and a multi-field forĭo not index any string longer than this value. Enabling this is a good idea on fields that are frequently used for Should global ordinals be loaded eagerly on refresh? Accepts true or false Should the field be stored on disk in a column-stride fashion, so that itĬan later be used for sorting, aggregations, or scripting? Accepts true
