-Rename stored procedures to follow SQL Server best practice `usp_` prefix convention for consistency and clarity.

 ## Implementation Approach
 
 ### 1. SQL Scripts (Modify Existing)
 
-Update scripts 040-043 directly with new procedure names:
+Update scripts 040-044 directly with new names:
 
+**Stored Procedures:**
 - `040_CreateSubmitSearchProcedure.sql` → `usp_SubmitSearch`
 - `041_CreateStartSearchProcedure.sql` → `usp_StartSearch`
 - `042_CreateCompleteSearchProcedure.sql` → `usp_CompleteSearch`
 - `043_CreateResetPartialSearchesProcedure.sql` → `usp_ResetPartialSearches`
 
+**Functions:**
+- `044_CreateMatchMisFunction.sql` → `fn_MatchMIS`
+
 ### 2. Docker Database (Manual Update)
 
 Since DbUp won't re-run already-executed scripts:
-1. Drop old procedures from Docker database
+1. Drop old procedures and functions from Docker database
 2. Execute updated CREATE statements directly
 
 ### 3. C# Constants Class (New File)
 
-Create `StoredProcedures.cs` in `JdeScoping.DataAccess`:
+Create `SqlObjects.cs` in `JdeScoping.DataAccess`:
 
 ```csharp
 namespace JdeScoping.DataAccess;
 
 /// <summary>
-/// Constants for stored procedure names.
+/// Constants for SQL stored procedure and function names.
 /// </summary>
-public static class StoredProcedures
+public static class SqlObjects
 {

     public const string SubmitSearch = "usp_SubmitSearch";
     public const string StartSearch = "usp_StartSearch";
     public const string CompleteSearch = "usp_CompleteSearch";
     public const string ResetPartialSearches = "usp_ResetPartialSearches";
     public const string ValidateSearchCriteria = "usp_ValidateSearchCriteria";
+
+    // Functions
+    public const string MatchMis = "fn_MatchMIS";
 }
 ```
 
-### 4. Repository Update
+### 4. C# Code Updates
 
-Update `LotFinderRepository.SearchManagement.cs` to use constant:
+**`LotFinderRepository.SearchManagement.cs`** - Use constant for stored procedure:
 
 ```csharp
 // Before
 await using var command = new SqlCommand("SubmitSearch", connection)
 
 // After
-await using var command = new SqlCommand(StoredProcedures.SubmitSearch, connection)
+await using var command = new SqlCommand(SqlObjects.SubmitSearch, connection)
+```
+
+**`MisQueryBuilder.cs`** - Use constant for function:
+
+```csharp
+// Before
+dbo.MatchMIS(c.WorkOrderNumber, ...)
+
+// After
+dbo.{SqlObjects.MatchMis}(c.WorkOrderNumber, ...)
 ```
