Configuring 'Search' for Service Backed Record

 Hi., I have an entity backed record with a grid view. As per the documentation, the 'Search' is applied across all columns of the grid.

Our requirement is to make the search happen against selective columns say 4 out of 10. For this purpose i am trying to create a service (Expression) backed record which has control over the search functionality.

 

My search works fine if i configure it against any one column but it stops working if i add multiple queryFilters (with OR condition).

Attaching the code for reference. Any pointer would be helpful.

  • Hi

    I am facing an issue with the general search.
    If any one of my column been fetched is of type other than text; then the record throws an error An eror occured while retrievng data for the record.
    By other type I mean, in the code, the code written for general search i.e.:

    a!queryFilter(
      field:"fullName",
      operator:"includes",
      value:local!generalSearch
    ) 

    Actually I want to do a general search on a field which is either integer or date.
    Any suggestions on what tweaking has to be done in the code to handle such scenarios.

    Below is full code for reference where launchDate is a date filed and accountNumber is an integer field
