Caml query to retrive keyword from rich text field

Question

hi friends
i am using below caml query to retrieve data from title field and Rich text field(Definition) 
<View>
<Query>
<Where>
<And>
<Or>
<Eq>
<FieldRef Name=\'Title\'/>
<Value Type=\'Text\'>'+letter+'</Value>
</Eq>
<Contains>
<FieldRef Name=\'Definition\' />
<Value Type=\'Note\'>'+letter+'</Value>

</Or>
<Neq>
<FieldRef Name=\'status\' />
<Value Type=\'Text\'>Not approved</Value>
</Neq>
</And>
</Where>
<OrderBy><FieldRef Name=\'Title\' /></OrderBy>
</Query>
</View>
this query is working fine. But it is retrieving some extra fields also which doesn't have the queried string. and even it is retrieving keyword from image urls which are present in rich text field. 
Please help me to retrieve key word from plain text of rich text field.

Hi,
According to your post, my understanding is that you want to use caml query to retrive keyword from rich text field
By design, when specifying a ViewFields clause, values for these fields are returned, together with a few system columns like ID, Created and Modified.
If you query rich text field, it will return the field with HTML tags.
To retrieve key word from plain text of rich text field, you need to use regular expression to remove the HTML tags.
You can use the code below:
using (SPSite site = new SPSite("http://sitename"))
using (SPWeb spWeb = site.OpenWeb())
SPList spList = spWeb.Lists.TryGetList("ListName");
SPQuery qry = new SPQuery();
if (spList != null)
qry.Query =
@" <Where>
<Contains>
<FieldRef Name='Rich_x0020_Text' />
<Value Type='Note'>caml</Value>
</Contains>
</Where>";
qry.ViewFields = @"<FieldRef Name='Title' /><FieldRef Name='Rich_x0020_Text' />";
SPListItemCollection listItems = spList.GetItems(qry);
foreach (SPListItem item in listItems)
string src = item["Rich_x0020_Text"].ToString();
Regex htmlReg = new Regex(@"<[^>]+>", RegexOptions.Compiled | RegexOptions.IgnoreCase);
src = htmlReg.Replace(src, string.Empty);
Console.WriteLine(src);
Console.ReadKey();
The result is as below:
