Hi,

1. how can i indexing other information with uploaded document ?
ex : i woluld like to an index infomation like user Name, User Creation Date, User Id with uploaded document when i'm creating a new user. and same information i have to use during searching indexed document as Extra Filter conditions. Is there a way to do this?

2. I have following Code in aspx page.
<searchengine:SearchBox ID="SearchBox1" runat="server" ResultPageURL="~/searchresults.aspx"
AutoCompleteQuery="true" AutoCompleteQueryShowNumberOfResults="false" RememberQuery="false"
AutoCompleteQueryRunSearchOnSelect="false" WatermarkText="Enter text here" CssClass="">

<SearchButton onclick="__doPostBack('SearchBox1','');" BorderWidth="" BorderColor=""
ForeColor="" BackColor="" Height="" Width="" CssClass="KeyotisearchBtn" type="button"
Value="Search" ID="ctl05"></SearchButton>

<QueryTextBox BorderWidth="" BorderColor="" ForeColor="" BackColor="" Height="" Width=""
CssClass="" type="text" ID="ctl04"></QueryTextBox>

</searchengine:SearchBox>

is there any way to handle searchengine's SearchButton Control click event from code behide, as like asp.net button Click event & from where i can set datasource to SearchResult control ?

3. can i use asp.net textBox & ajax date Control for filtering results ?

4. other asp.net control from SearchResult page get reinitialize after click of SearchButton.
ex : ASP.NET textBox value not find in Page_Load Event after click of SearchButton.
