+- A recent compiler (LLVM clang 6 or better, GNU GCC 7.4 or better, Xcode 11 or better) on a 64-bit (PPC, ARM or x64 Intel/AMD) POSIX systems such as macOS, freeBSD or Linux. We require that the compiler supports the C++11 standard or better.
+- Visual Studio 2017 or better under 64-bit Windows. Users should target a 64-bit build (x64 or ARM64) instead of a 32-bit build (x86). We support the LLVM clang compiler under Visual Studio (clang-cl) as well as as the regular Visual Studio compiler. For better release performance (both compile time and execution time), we recommend Visual Studio users adopt LLVM (clang-cl). We also support MinGW 64-bit under Windows.
 
-- A recent compiler (LLVM clang 6 or better, GNU GCC 7.4 or better, Xcode 11 or better) on POSIX systems such as macOS, FreeBSD or Linux. We require that the compiler supports the C++11 standard or better. We test the library on a big-endian system (IBM s390x with Linux).

For better release performance (both compile time and execution time), we recommend Visual Studio users adopt LLVM (clang-cl). We also support MinGW 64-bit under Windows.
 
 Support for AVX-512 require a processor with AVX512-VBMI2 support (Ice Lake or better, AMD Zen 4 or better) under a 64-bit system and a recent compiler (LLVM clang 6 or better, GCC 8 or better, Visual Studio 2019 or better). You need a correspondingly recent assembler such as gas (2.30+) or nasm (2.14+): recent compilers usually come with recent assemblers. If you mix a recent compiler with an incompatible/old assembler (e.g., when using a recent compiler with an old Linux distribution), you may get errors at build time because the compiler produces instructions that the assembler does not recognize: you should update your assembler to match your compiler (e.g., upgrade binutils to version 2.30 or better under Linux) or use an older compiler matching the capabilities of your assembler.

+## Using `at_path_with_wildcard` for JSONPath Queries
+
+The `at_path_with_wildcard` function in simdjson extends the JSONPath querying capabilities by supporting wildcard expressions (`*`) in JSON paths. This allows users to retrieve multiple elements from a JSON document in a single query. For example, you can use `$.address.*` to fetch all fields within the `address` object or `$.phoneNumbers[*].numbers[*]` to retrieve all phone numbers across multiple objects in an array.
+
+The `*` wildcard matches all elements at a specific level. For instance, `$.address.*` retrieves all key-value pairs in the `address` object, while `$.*.streetAddress` fetches all `streetAddress` fields across objects at the root level.  You can combine wildcards with array indexing. For example, `$.phoneNumbers[*].numbers[1]` retrieves the second number from each `numbers` array in the `phoneNumbers` array. If no elements match the wildcard query, the function returns an empty result. For instance, querying `$.empty_object.*` or `$.empty_array.*` will yield an empty set.
+
+### Example Usage
+
+Here is an example demonstrating the use of `at_path_with_wildcard`:
+
+```cpp
+simdjson::padded_string json_string = R"(
+{
+  "firstName": "John",
+  "lastName": "doe",
+  "age": 26,
+  "address": {
+    "streetAddress": "naist street",
+    "city": "Nara",
+    "postalCode": "630-0192"
+  },
+  "phoneNumbers": [
+    {
+      "type": "iPhone",
+      "numbers": ["0123-4567-8888", "0123-4567-8788"]
+    },
+    {
+      "type": "home",
+      "numbers": ["0123-4567-8910"]
+    }
+  ]
+})"_padded;
+
+dom::parser parser;
+dom::element parsed_json = parser.parse(json_string);
+std::vector<dom::element> values;
+
+// Fetch all fields in the address object
+auto error = parsed_json.at_path_with_wildcard("$.address.*").get(values);
+if(error) {
+  // do something
+}
+for (auto &value : values) {
+  std::string_view field;
+  error = value.get(field);
+  if(error) {
+    // do something
+  }
+  std::cout << field << std::endl;
+}
+
+// Fetch all phone numbers
+error = parsed_json.at_path_with_wildcard("$.phoneNumbers[*].numbers[*]").get(values);
+if(error) {
+  // do something
+}
+for (auto &value : values) {
+  std::string_view number;
+  error = value.get(number);
+  if(error) {
+    // do something
+  }
+  std::cout << number << std::endl;
+}
+```
+
+This function is particularly useful for extracting data from complex JSON structures with nested arrays and objects. By leveraging wildcards, you can simplify your queries and reduce the need for multiple iterations.
