Do you want to implement Lucene search in Sitecore and
unable to get where to start exactly? Fuck all those theory on internet and
refer this straight forward guide.
Rename “\Website\App_Config\IncludeSitecore.ContentSearch.Lucene.Index.Master.config”
to “IncludeSitecore.ContentSearch.Lucene.Index.Surendra.config”
Open and do the following highlighted config changes.
Basically add your template IDs which do you want to show as a search result

Open Sitecore Desktop version -> Control Panel ->
Indexing – Indexing Manager -> Checked only “Surendra” Instance -> Next -> Finish [There must be some units processed at this stage.]
Goto IIS and recycle application pool of your site.
Create Search content item and set Search control
layout with this content item.
Add below HTML and C# code in this Search page
<asp:TextBox runat="server" ID="txtsearch" ></asp:TextBox>
<asp:Button runat="server" ID="btnSearch" Text="Search" OnClick="btnSearch_Click" CssClass="searchbtn" />
<ul>
<asp:Repeater ID="rptEvents" runat="server">
<ItemTemplate>
<asp:HyperLink NavigateUrl="<%# Sitecore.Links.LinkManager.GetItemUrl((Item)Container.DataItem) %>" runat="server">
<li>
<strong>
Title
Write your
HTML code here
</strong>
</li>
</asp:HyperLink>
</ItemTemplate>
