analyzer: the analyzer used for indexing
search_analyzer: the analyzer used for searching
index_options: controls what information is added to the inverted index,
available options are:
docs: Only the doc number is indexed. Can answer the question
Does this term exist in this field?freqs: Doc number and term frequencies are indexed. Term frequencies are
used to score repeated terms higher than single terms.positions (default): Doc number, term frequencies, and term positions
(or order) are indexed. Positions can be used for proximity or phrase queries.offsets: Doc number, term frequencies, positions, and start and end character
offsets (which map the term back to the original string) are indexed. Offsets
are used by the unified highlighter to speed up highlighting.
realtime: For non-object fields, enabling this option allows the field to
support real-time search. For object fields, the realtime parameter overrides
the realtime settings of its sub-fields.
index: For non-object field, if set, Pizza would build index for it to make
it searchable. For object fields, the index parameter overrides
the index settings of its sub-fields.
fields: It is often useful to index the same field in different ways for
different purposes. This is the purpose of multi-fields
properties: nested sub-fields
