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 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 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 fielddata() -> Option<bool>
Can the field use in-memory fielddata for sorting, aggregations, or scripting? Accepts true
or false
(default). Read more
fn fielddata_frequency_filter() -> Option<FieldDataFrequencyFilter>
Expert settings which allow to decide which values to load in memory when fielddata
is enabled. By default all values are loaded. 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 position_increment_gap() -> Option<u32>
The number of fake term position which should be inserted between each element of an array of strings. Defaults to the position_increment_gap
configured on the analyzer which defaults to 100
. 100
was chosen because it prevents phrase queries with reasonably large slops (less than 100
) from matching terms across field values. 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 search_quote_analyzer() -> Option<&'static str>
The analyzer that should be used at search time when a phrase is encountered. Defaults to the search_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 term_vector() -> Option<TermVector>
Whether term vectors should be stored for an analyzed
field. Defaults to No
. Read more

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