 ## Description
 The Ansible Module `software_center_download` automates downloading files from the SAP Software Center.
 - It can find a file using a search query or download it directly using a specific download link and filename.
+- Supports wildcard search to find and download specific versions (oldest/newest) from multiple available versions.
 - If a file is not found via search, it can look for alternative versions.
 - It supports checksum validation to ensure file integrity and avoid re-downloading valid files.
 - The module can also perform a dry run to check for file availability without downloading.

 ## Execution
 
+### Wildcard Search Format
+The module supports wildcard search to find files across multiple versions. This is useful when you want to download the latest (or oldest) version of a software package without knowing the exact version number.
+
+**Format:** `PREFIX*-ID.EXT`
+
+Where:
+
+- `PREFIX`: The software name prefix (e.g., `SAPEXE`, `SAPHOSTAGENT`).
+- `*`: Single wildcard representing the version number.
+- `-`: Dash separator (required).
+- `ID`: File ID number (e.g., `80002630`).
+- `.EXT`: File extension (e.g., `.SAR`, `.EXE`).
+
+> **NOTE:** File ID is unique number that represents combination of component and platform version. 
+
+**Requirements:**
+- The parameter `search_alternatives: true` must be enabled.
+- Only one wildcard (`*`) is allowed per query.
+- File format must include both dash and extension according to pattern above.
+- Use `deduplicate` parameter to select oldest (`first`) or newest (`last`) version.
+
+**Examples:**
+- `SWPM20SP2*-80003424.SAR` - Matches all available SWPM20 versions starting with `2` (SWPM20SP23, SWPM20SP24, etc.) for `Linux on x86_64 64bit` (80003424).
+- `SAPEXE_10*-80002630.SAR` - Matches all available SAPEXE_10 versions starting with `10` (SAPEXE_10, SAPEXE_100, SAPEXE_1000, etc.) for `Linux on Power LE 64bit` (80002630).
+- `SAPHOSTAGENT*-80004822.SAR` - Matches all available SAPHOSTAGENT versions for `Linux on x86_64 64bit` (80004822).
+
+**Special Files:**
+Some SAP media files don't follow the standard naming pattern and require exact filenames:
+
+- `S4CORE107_INST_EXPORT_1.zip`
+- `KD75783.SAR`
+- `19118000000000009032` (SAP Media downloaded with ID instead of Title).

 ### Execution Flow
 The module follows a sophisticated logic flow to determine whether to download, skip, or fail. Here is a simplified breakdown of the decision-making process:
