A multi-field string mapping.
Fields
analyzer: Option<&'static str>
The analyzer which should be used for analyzed string fields,
both at index-time and at search-time (unless overridden by the search_analyzer
).
Defaults to the default index analyzer, or the standard
analyzer.
doc_values: Option<bool>
Should the field be stored on disk in a column-stride fashion,
so that it can later be used for sorting, aggregations, or scripting?
Accepts true
(default) or false
.
eager_global_ordinals: Option<bool>
Should global ordinals be loaded eagerly on refresh?
Accepts true
or false
(default).
Enabling this is a good idea on fields that are frequently used for (significant) terms aggregations.
include_in_all: Option<bool>
Whether or not the field value should be included in the _all
field?
Accepts true or false.
Defaults to false
if index is set to no
, or if a parent object field sets include_in_all
to false.
Otherwise defaults to true
.
ignore_above: Option<u32>
The maximum number of characters to index. Any characters over this length will be ignored.
index: Option<bool>
Should the field be searchable? Accepts true
(default) or false
.
index_options: Option<IndexOptions>
What information should be stored in the index, for search and highlighting purposes. Defaults to Positions
.
norms: Option<bool>
Whether field-length should be taken into account when scoring queries. Accepts true
(default) or false
.
store: Option<bool>
Whether the field value should be stored and retrievable separately from the _source
field.
Accepts true
or false
(default).
search_analyzer: Option<&'static str>
The analyzer that should be used at search time on analyzed fields. Defaults to the analyzer setting.
similarity: Option<&'static str>
Which scoring algorithm or similarity should be used.
Defaults to "classic"
, which uses TF/IDF.
