Search API not working while using server-side processing

Search API not working while using server-side processing

SKCSKC Posts: 33Questions: 10Answers: 0

I was initially using client-side processing and had implemented the Search API mentioned in the following link :
https://datatables.net/examples/api/regex.html
The search filters for each column worked fine back then.

Now I have switched to server-side processing. But now the search-api doesn't seems to work.
Currently I'm fetching data from SQL DB. While searching through the seach-api filters the data remains unaffected.
The default Search box is working fine.

Is there any way to solve this issue?

    With server-side processing, searching would be carried out by your server-side processing code - i.e. the code which is fetching data from the db.

    Check the "server-side" code in the "Examples".

    Can anyone share how to implement Search API ( similar to this https://datatables.net/examples/api/regex.html) while using server-side processing.

    Just as I've mentioned above my data is stored in SQL Server DB.

    Thanks for the reply tangerine... But I couldn't get it done

    What does that mean? Are you learning from the example I pointed to? How far have you got?

    You have to provide a lot more information if you expect some help.

    I'm not aware of anyone having implemented regular expression searching with MySQL for DataTables server-side processing. I don't doubt that has been done, but I don't have the code for it. The main problem with it is that when you are dealing with enough records to warrant server-side processing, performance of regex becomes an issue.

    You would need to refer to the MySQL regex manual and update your server-side processing script to support that.

    Actually I'm using SQL Server DB.

    I've implemented a MVC architecture.

    Here's my JS code :

    $(document).ready(function () {
    
        $('#searchResult').DataTable(
             {
                   "processing": true,    // to show progress bar
                 "serverside": true,    // enables server-side processing
                 "filter": true,            // this is for disable filter (search box)
                 "ordermulti": false, // disables multiple column at once
                 "ajax":
                 {
                     "url": "/ChopRequest.Web/Search/GetSearchResults",
                     "type": "POST",
                     "datatype": "json"
                 },
    
                 "columns":
                 [
                         { "data": "ChopRequestNo" },
                         { "data": "Description" },
                         { "data": "CreatedBy" },
                         { "data": "CompanyCodeName" },
                         { "data": "DocTypeName" },
                         { "data": "DocTypeDescription" },
                         { "data": "ReferenceNo" },
                         { "data": "Status" },
      ]
             });

    Here's my script which gets data from the UI :

    function searchFilters() {
        var search = {
            ChopRequestNo: $('#txtChopRequestNo').val(),
            ReferenceNo: $('#txtReferenceNo').val(),
            CreatedBy: $('#txtCreatedBy').val(),
            Chopper: $('#txtChopper').val(),
            Manager: $('#txtManager').val(),
            LeagalApprover: $('#txtLeagalApprover').val(),
            FinanceApprover: $('#txtFinanceApprover').val(),
            SystemAdmin: $('#txtSystemAdmin').val(),
            VP: $('#ddlVP').val(),
            DocumentType: $('#ddlDocumentType').val(),
            CompanyCode: $('#ddlCompanyCode').val(),
            CreatedOn: $('#createdOn').val(),
            CompletedOn: $('#completedOn').val(),
        };
    
        $.post(postTo,
            {
                obj: JSON.stringify(search),
            },
            function (data) {
                if (data.Result == "OK") {
                    alert("Search Successfull!");
                } else {
                    alert("Error While Searching");
                }
            }, "json");
    
    }
    

    Now how do I proceed further??

    Here is the Microsoft documentation for SQL server's regex.

    Since you are using server-side processing, you would need to modify your GetSearchResults script to do the regex search.

    I see a lot of people struggling with ServerSideProcessing and the need for alterhnatives to (option1|option2|option3) type regular expressions. Could you possible show an example of how one would build a result table from successive table.column().search() results before issueing a table.draw() command?

  • allanallan Posts: 63,350Questions: 1Answers: 10,443 Site admin

    Do you mean like a WHERE ... OR ...? The built in server-side processing for the Editor scripts won't do that I'm afraid, but you could use a custom condition (Where() and OrWhere()) to do exactly that based on a split string.

    But I'm not certain that is what you are looking for?

    Hmmmm, interesting. I will try this over the weekend and summarize the application for others thereafter. Thanks Allan - I hope you enjoy your weekend.
