fn 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. Read more
fn boost() -> Option<f32>
Field-level index time boosting. Accepts a floating point number, defaults to 1.0
.
fn 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
. Read more
fn 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. Read more
fn fields() -> Option<BTreeMap<&'static str, StringField>>
Multi-fields allow the same string value to be indexed in multiple ways for different purposes, such as one field for search and a multi-field for sorting and aggregations, or the same string value analyzed by different analyzers. Read more
fn 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
. Read more
fn ignore_above() -> Option<u32>
The maximum number of characters to index. Any characters over this length will be ignored. Read more
fn index() -> Option<bool>
Should the field be searchable? Accepts true
(default) or false
.
fn index_options() -> Option<IndexOptions>
What information should be stored in the index, for search and highlighting purposes. Defaults to Positions
.
fn norms() -> Option<bool>
Whether field-length should be taken into account when scoring queries. Accepts true
(default) or false
.
fn null_value() -> Option<&'static str>
Accepts a string
value which is substituted for any explicit null values. Defaults to null
, which means the field is treated as missing. Read more
fn store() -> Option<bool>
Whether the field value should be stored and retrievable separately from the _source
field. Accepts true
or false
(default). Read more
fn search_analyzer() -> Option<&'static str>
The analyzer that should be used at search time on analyzed fields. Defaults to the analyzer setting. Read more
fn similarity() -> Option<&'static str>
Which scoring algorithm or similarity should be used. Defaults to "classic"
, which uses TF/IDF. Read more

fn fmt(&self, __arg_0: &mut Formatter) -> Result<(), Error>
Formats the value using the given formatter.
