 ```{applies_to}

 With any new indices created, token pruning will be turned on by default with appropriate defaults. You can control this behaviour using the optional `index_options` parameters for the field:

     * Exclude the field from [_source](/reference/elasticsearch/rest-apis/retrieve-selected-fields.md#source-filtering).
     * Use [synthetic `_source`](/reference/elasticsearch/mapping-reference/mapping-source-field.md#synthetic-source).
 
-index_options {applies_to}`stack: preview 9.1`
+index_options {applies_to}`stack: ga 9.1`
 :   (Optional, object) You can set index options for your  `sparse_vector` field to determine if you should prune tokens, and the parameter configurations for the token pruning. If pruning options are not set in your [`sparse_vector` query](/reference/query-languages/query-dsl/query-dsl-sparse-vector-query.md), Elasticsearch will use the default options configured for the field, if any.
 
 Parameters for `index_options` are:
 
-`prune` {applies_to}`stack: preview 9.1`
+`prune` {applies_to}`stack: ga 9.1`
 :   (Optional, boolean) Whether to perform pruning, omitting the non-significant tokens from the query to improve query performance. If `prune` is true but the `pruning_config` is not specified, pruning will occur but default values will be used. Default: true.
 
-`pruning_config` {applies_to}`stack: preview 9.1`
+`pruning_config` {applies_to}`stack: ga 9.1`
 :   (Optional, object) Optional pruning configuration. If enabled, this will omit non-significant tokens from the query in order to improve query performance. This is only used if `prune` is set to `true`. If `prune` is set to `true` but `pruning_config` is not specified, default values will be used. If `prune` is set to false but `pruning_config` is specified, an exception will occur.
 
     Parameters for `pruning_config` include:
 
-    `tokens_freq_ratio_threshold` {applies_to}`stack: preview 9.1`
+    `tokens_freq_ratio_threshold` {applies_to}`stack: ga 9.1`
     :   (Optional, integer) Tokens whose frequency is more than `tokens_freq_ratio_threshold` times the average frequency of all tokens in the specified field are considered outliers and pruned. This value must between 1 and 100. Default: `5`.
 
-    `tokens_weight_threshold` {applies_to}`stack: preview 9.1`
+    `tokens_weight_threshold` {applies_to}`stack: ga 9.1`
     :   (Optional, float) Tokens whose weight is less than `tokens_weight_threshold` are considered insignificant and pruned. This value must be between 0 and 1. Default: `0.4`.

@@ -200,6 +200,7 @@ The following are the current limitations with `LOOKUP JOIN`:
 * Indices in [`lookup` mode](/reference/elasticsearch/index-settings/index-modules.md#index-mode-setting) are always single-sharded.
 * Cross cluster search is unsupported initially. Both source and lookup indices must be local.
 * Currently, only matching on equality is supported.
-* `LOOKUP JOIN` can only use a single match field and a single index. Wildcards, aliases, datemath, and datastreams are not supported.
+* `LOOKUP JOIN` can only use a single match field and a single index. Wildcards are not supported.
+  * Aliases, datemath, and datastreams are supported, as long as the index pattern matches a single concrete index {applies_to}`stack: ga 9.1.0`.
 * The name of the match field in `LOOKUP JOIN lu_idx ON match_field` must match an existing field in the query. This may require `RENAME`s or `EVAL`s to achieve.
 * The query will circuit break if there are too many matching documents in the lookup index, or if the documents are too large. More precisely, `LOOKUP JOIN` works in batches of, normally, about 10,000 rows; a large amount of heap space is needed if the matching documents from the lookup index for a batch are multiple megabytes or larger. This is roughly the same as for `ENRICH`.
