Introduction

This article will show you how to develop a simple multi-column, multi-keyword, and multi option search engine; it can be used for any database driven application that requires search engine facility.

Figure 1

It is worth mentioning that at the time I was writing this article I found Kelly Gafford single column, multi-word database search sample code at planetsourcecode written in Classic ASP very useful which gave me the idea of how to go ahead.

I like to know if you can help with paging and sorting the results from the client side? I didn't see any page methods in your code.

As example if search return 30 records, for the first page i want to setup display like 'You are viewing 1-10' and when user click on the next page it will display 'You are viewing 11-20' and so on. Would you please advise how can i do that.

Hi Khalid,
Thanks for correcting me. It was my fault, I did not think about this before. It is working fine now. I love it. Did you try repeater for this type of search function? I think that will be good as well.

Thanks again for your help.

Tajuddin

Hi Tajuddin,
Change the doSearch method according to the sample I provided in my previous post. as you can see in the sample it uses DataSet Classes in place of DataReader because DataReader doesn't support Paging unless you do some extra coding.

thanks

Hi Khalid,
Thanks for your prompt response. I have tried that but it does not return any records now. I have added -
protected void CustomersGridView_SelectedIndexChanged(object sender, EventArgs e)
{

}
protected void CustomersGridView_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
{

}
protected void CustomersGridView_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
CustomersGridView.PageIndex = e.NewPageIndex;
CustomersGridView.DataBind();
System.Threading.Thread.Sleep(1000);
string strCriteria = SearchCriteriaList.SelectedItem.Value;
doSearch(SearchTextBox.Text.Trim(), strCriteria);
RecordCount.Visible = true;

}
in the cs file and added -
AllowPaging="true" onpageindexchanging="CustomersGridView_PageIndexChanging"
onselectedindexchanging="CustomersGridView_SelectedIndexChanging"
in the gridview tag but did not work. I could find any problem. Could you suggest me what i did wrong..

Thanks again for your help.

Regards,

Tajuddin

Hi Khalid,
I have implemented this search function in my website and it works fine. Fantastic idea. I am having a bit problem when trying to enable pagination. For instance, I have more than 1000 records in my database. So when user search it returns large number of record. How can I set up pagination so that it will populatate muliple page with link like form view or details view. Could you please provide me some suggestions.

Thanks brother,

Yes it does, but you will need to use OleDb classes inside of System.Data.OleDb namespace for data retrieval, and use Query instead of View.
Check out this link for connecting with Ms Access.

Hi Tajuddin,
What Database System do you use?, the query I have provided should work fine.
If you are using SQL server right click on the Northwind Database then "New Query" then paste the code I have provided and click on the "Execute" Button in the toolbar.

thanks

Thank you Wayne, I am glad that you liked the article.
For paging you will need to use DataSet classes since DataReader doesnt not support paging and filtering.
I have updated the sample in which paging is enabled you can download the new sample from the link bellow:

Nice article - helped me get my head around a few things.

Any chance you could add some code to allow paging - tried the simple AllowPaging="True" but obviously this didn't work. Been looking for a way to do this but as a newbie am getting stuck!

This method is useful for small apps i think but for large web portals you must use Sql Server 2005 fulltextsearch .
Maybe it would be interesting to build implementation
fulltextsearch using Linq.
There isnt any article on using linq for fulltextsearch,and you cant use linq for fulltextsearch I think.
Maybe would be great to build some helper classes to do that.
