index.shard.check_on_startup | Whether the index's shards should be checked for corruption. Available options are `false` (do not check for corruption), `checksum` (check for physical corruption), and `true` (check for both physical and logical corruption). Default is `false`.
index.codec | The compression type to use to compress stored data. Available values are `best_compression` and `default`.
index.routing_partition_size | The number of shards a custom routing value can go to. Routing helps an imbalanced cluster by relocating values to a subset of shards rather than just a single shard. To enable, set this value to greater than 1 but less than `index.number_of_shards`. Default is 1.
index.soft_deletes_enabled | Whether to retain a history of operations performed on the index.
index.soft_deletes.retention_lease.period | The maximum amount of time to retain a shard's history of operations. Default is `12h`.
index.load_fixed_bitset_filters_eagerly | Indicates whether cached filters should be pre-loaded for nested queries. Available options are `true` and `false`. Default is `true`.
index.load_fixed_bitset_filters_eagerly | Whether OpenSearch should pre-load cached filters. Available options are `true` and `false`. Default is `true`.
index.hidden | Whether the index should be hidden. Hidden indices are not returned as part of queries that have wildcards. Available options are `true` and `false`. Default is `false`.

Setting | Description
:--- | :---
index.number_of_replicas | The number of replica shards each primary shard should have. For example, if you have 4 primary shards and set `index.number_of_replicas` to 3, the index has 12 replica shards. Default is 1.
index.auto_expand_replicas | Automatically expands the number of replicas based on the amount of data nodes in the cluster. Specify a lower bound and upper limit (for example, 0-9), or `all` for the upper limit. For example, if you have 5 data nodes and set `index.auto_expand_replicas` to 0-3, then the cluster does not autoamtically add another replica shard. However, if you set this value to `0-all` and add 2 more nodes for a total of 7, the cluster will expand to now have 6 replica shards. Default is disabled.

index.search.idle.after | Amount of time a shard should wait for a search or get request until it goes idle. Default is `30s`.
index.refresh_interval | How often the index should refresh, which publishes its most recent changes and makes them available for searching. Can be set to `-1` to disable refreshing. Default is `1s`.
index.max_result_window | The maximum value of `from` + `size` for searches to the index. `from` is the starting index to search from, and `size` is the amount of results to return. Default: 10000.
index.max_inner_result_window | The maximum value of `from` + `size` for inner hits definitions and top hits aggregations to the index. `from` is the starting index to search from, and `size` is the amount of top hits to return. Default is 100.
index.max_inner_result_window | aximum value of `from` + `size` to return nested search hits and most relevant document aggregated during the query. `from` is the starting index to search from, and `size` is the amount of top hits to return. Default is 100.
index.max_rescore_window | The maximum value of `window_size` for rescore requests to the index. Rescore requests reorder the index's documents and return a new score, which can be more precise. Default is the same as index.max_inner_result_window or 10000 by default.
index.max_docvalue_fields_search | Maximum amount of `docvalue_fields` allowed in a query. Default is 100.
index.max_script_fields | Maximum amount of `script_fields` allowed in a query. Default is 32.
index.max_ngram_diff | Maximum allowed difference between `min_gram` and `max_gram` values for `NGramTokenizer` and `NGramTokenFilter`. Default is 1.
index.max_shingle_diff | Maximum allowed difference between `max_shingle_size` and `min_shingle_size` for the `shingle` token filter. Default is 3.
index.max_refresh_listeners | Maximum amount of refresh listeners available on the index's shards.
index.max_script_fields | Maximum amount of`script_fields` allowed in a query. Default is 32.
index.max_ngram_diff | Maximum difference between `min_gram` and `max_gram` values for `NGramTokenizer` and `NGramTokenFilter` fields. Default is 1.
index.max_shingle_diff | Maximum difference between `max_shingle_size` and `min_shingle_size` to feed into the `shingle` token filter. Default is 3.
index.max_refresh_listeners | Maximum amount of refresh listeners each shard is allowed to have.
index.analyze.max_token_count | Maximum amount of tokens that can return from the `_analyze` API operation. Default is 10000.
index.highlight.max_analyzed_offset | The maximum amount of characters that will be analyzed in a highlight request. Default is 1000000.
index.max_terms_count | The maximum amount of terms that can be used in a terms query. Default is 65536.
index.highlight.max_analyzed_offset | The amount of characters a highlight request can analyze. Default is 1000000.
index.max_terms_count | The maximum amount of terms a terms query can accept. Default is 65536.
index.max_regex_length | The maximum character length of regex that can be in a regexp query. Default is 1000.
index.query.default_field | A field or list of fields that OpenSearch uses in queries in case a field isn't specified in the parameters.
index.routing.allocation.enable | Specifies options for the index's shard allocation. Available options are `all` (allow shard allocation for all shards), `primaries` (allow shard allocation only for primary shards), `new_primaries` (allow shard allocaiton only for new primary shards), and `none` (do not allow shard allocation). Default is `all`.
index.routing.allocation.enable | Specifies options for the index’s shard allocation. Available options are all (allow allocation for all shards), primaries (allow allocation only for primary shards), new_primaries (allow allocation only for new primary shards), and none (do not allow allocation). Default is all.
index.routing.rebalance.enable - Shard rebalancing for the index. Available options are `all` (allow rebalancing for all shards), `primaries` (allow rebalancing only for primary shards), `replicas` (allow rebalancing only for replicas), and `none` (do not allow rebalancing). Default is `all`.
index.routing.rebalance.enable | Enables shard rebalancing for the index. Available options are `all` (allow shard rebalancing for all shards), `primaries`, (allow shard rebalancing only for primary shards), `replicas` (allow shard rebalancing only for replicas), and `none` (do not allow shard rebalancing). Default is `all`.
index.gc_deletes | Amount of time to retain a deleted document's version number. Default is `60s`.
index.default_pipeline | The default ingest node pipeline for the index. If the default pipeline is set and the pipeline does not exist, then index requests fail. The pipeline name `_none` specifies that the index does not have an ingest pipeline.
