Mapping: OMGT Advanced Search

1. Feature Reference

• Document: AdvancedSearch.feature

2. Technical Mapping

Gherkin Step	Code Component	Technical Detail
I enter "Rossi" in the "Name" field	SearchOrderOMGTDto.CustomerName	Captured in AdvancedSearchController.GetNavigateResult
I click "Search"	AdvancedSearchController.GetNavigateResult	Triggers OrderTravelProductService.GetOrderTravelProductList
the system should retrieve results	OrderAdvancedSearchQueryBuilder.BuildQuery	Constructing LINQ for OrderTravelProductOMGTList.OMGTOrderInProgressQuery
I select "Excel export"	AdvancedSearchController.Export	Constructs MassActionDTO with EntityName = "OrderTravelProductOMGT"
a file should be generated	MassActionHandler.ExportExcel	Uses EITTabularFile for generation

3. Data Context

• Primary Entity: OrderTravelProductOMGT
• Search View: OrderTravelProductSearchViewList (SQL View)
• Mass Action Service: WepOmgtOrderProductComponentService (inherited by concrete services)

4. Known Constraints

• Churn: The query builder has high churn and complexity (L5763 in OrderAdvancedSearchQueryBuilder.cs).
• Performance: In-memory filtering in FinaliseQuery is a critical bottleneck.
