 ### Group metadata events
 
-These events contain the group id in a `d` tag instead of the `h` tag. They MUST be created by the relay master key only (as stated by the [NIP-11](11.md) `"self"` pubkey) and a single instance of each (or none) should exist at all times for each group. They are merely informative but should reflect the latest group state (as it was changed by moderation events over time).

 Relays SHOULD perform matching against `content` event field, and MAY perform
 matching against other fields if that makes sense in the context of a specific kind. 
 
-Results SHOULD be returned in descending order by quality of search result (as defined by the implementation),
-not by the usual `.created_at`. The `limit` filter SHOULD be applied after sorting by matching score.
 A query string may contain `key:value` pairs (two words separated by colon), these are extensions, relays SHOULD ignore 
 extensions they don't support.
 
+### Query Expression Extensions
+
+Relays MAY support query expressions with boolean operators and filter attributes. When supported, this MUST be advertised in NIP-11:
+
+```json
+{
+  "supported_nips": [50],
+  "nip50_search": {
+    "boolean_operators": true,
+    "filter_attributes": ["limit", "since", "until"]
+  }
+}
+```
+
+When `boolean_operators` is `true`, relays SHOULD support:
+
+- Terms split by whitespace (implicit AND)
+- Double quotes for phrase matching: `"hello world"`
+- Boolean operators: `AND`, `OR` (uppercase, case-sensitive)
+- Parentheses for grouping: `(cat AND dog) OR bird`
+- Operator precedence: `AND` binds tighter than `OR`
+
+Examples:
+- `hello world` → both terms required (implicit AND)
+- `hello OR world` → either term matches
+- `cat AND (dog OR bird)` → "cat" plus either "dog" or "bird"
+
+When `filter_attributes` is present, relays SHOULD support filter attributes in the query string:
+
+- `limit:<number>` - limit number of results (e.g., `limit:50`)
+- `since:<unix timestamp>` - filter events after timestamp (e.g., `since:1609459200`)
+- `until:<unix timestamp>` - filter events before timestamp (e.g., `until:1640995200`)
+
+Examples:
+- `nostr limit:50` → search "nostr" and return up to 50 results
+- `bitcoin since:1609459200` → search "bitcoin" for events after the specified time
+- `cats OR dogs limit:100 since:1640995200` → combined query with filters
+
+Results SHOULD be returned in descending order by quality of search result (as defined by the implementation),
+not by the usual `.created_at`. The `limit` filter SHOULD be applied after sorting by matching score.
+
 Clients may specify several search filters, i.e. `["REQ", "", { "search": "orange" }, { "kinds": [1, 2], "search": "purple" }]`. Clients may 
 include `kinds`, `ids` and other filter field to restrict the search results to particular event kinds.

-- Kind `34236` for _addressable short videos_
