It sound like you want to do a basic user search?
Here is how we do it in .NET for our custom user search portlet:
private IPortletContext     portletContext;
protected DataGrid dgResults;
private DataTable resultsTable = null;
protected System.Web.UI.WebControls.Label lblMessage;
protected System.Web.UI.HtmlControls.HtmlTableCell resultsCell;
private void Page_Load(object sender, System.EventArgs e)
portletContext     = PortletContextFactory.CreatePortletContext(Request,Response);
string searchString;
searchString = Request.QueryString["TextName"];
// build up a search request for the matching users
IRemoteSession prcSession          = portletContext.GetRemotePortalSession();
ISearchFactory searchFactory          = prcSession.GetSearchFactory();
IPortalSearchRequest searchRequest     = searchFactory.CreatePortalSearchRequest();
IUserManager userManager = prcSession.GetUserManager();
ObjectClass[] objectTypes = {ObjectClass.User};
               searchRequest.SetObjectTypesToSearch(objectTypes);
if( !searchString.Equals("")){
IFilterClause generalClause          = searchFactory.CreateAndFilterClause();
                    generalClause.AddStatement(PlumtreeField.NAME, Operator.Contains, searchString);
Field[] fieldsToReturn = {
(Field) PortalField.ForID(156), // 156 = Company
(Field) PortalField.ForID(157), // 157 = Address
(Field) PortalField.ForID(163), // 163 = Address2
(Field) PortalField.ForID(162), // 162 = City
(Field) PortalField.ForID(159), // 159 = State
(Field) PortalField.ForID(158), // 158 = Zip Code
(Field) PortalField.ForID(222), // 222 = Location
                    searchRequest.SetFieldsToReturn(fieldsToReturn);
                    searchRequest.SetQuery("*", generalClause);
ISearchResponse searchResponse = searchRequest.Execute();
ISearchResultSet resultSet = searchResponse.GetResultSet();
                    System.Collections.IEnumerator results = resultSet.GetResults();
// build up our data table, we will bind this to the data grid once populated
resultsTable = new DataTable("ResultsTable");
System.Data.DataColumn key = new DataColumn("name", System.Type.GetType("System.String"));
                    resultsTable.Columns.Add(key);
                    resultsTable.Columns.Add("title", System.Type.GetType("System.String"));
                    resultsTable.Columns.Add("phonenumber", System.Type.GetType("System.String"));
                    resultsTable.Columns.Add("address", System.Type.GetType("System.String"));
System.Data.DataColumn[] keycolumn = { key };
resultsTable.PrimaryKey = keycolumn;
while (results.MoveNext())
                         IPortalSearchResult result = (IPortalSearchResult) results.Current;
//string viewProfileLink = "<pt:standard.openerlink pt:objectid='" + result.GetObjectID() + "' " +
                         //     "pt:classid='1' pt:mode='2' target='userProfileResult'>" + result.GetName() + "</pt:standard.openerlink>";
string address = result.GetFieldAsString((Field) PortalField.ForID(157));
string address2 = result.GetFieldAsString((Field) PortalField.ForID(163));
string city = result.GetFieldAsString((Field) PortalField.ForID(162));
string state = result.GetFieldAsString((Field) PortalField.ForID(159));
string zip = result.GetFieldAsString((Field) PortalField.ForID(158));
string location =result.GetFieldAsString((Field) PortalField.ForID(222));
string fullAddress = "";
//added in location
if(location !="" &&location!=null) fullAddress+= location+"<br/>";
if(address != "" && address != null) fullAddress += address + "<br/>";
if(address2 != "" && address2 != null) fullAddress += address2 + "<br/>";
fullAddress += city + " " + state + " " + zip;
string name = "<a href='mailto:" result.GetFieldAsString((Field) PortalField.ForID(258))"'>"+result.GetName()+"</a>";
// add all of the users to our results table
object[] newUserRow = {     //result.GetName(), 
                                        name,
                                        result.GetFieldAsString((Field) PortalField.ForID(153)), // Title
                                        result.GetFieldAsString((Field) PortalField.ForID(152)), // Phone
                                        fullAddress,
                         resultsTable.Rows.Add(newUserRow);
// bind the table to the grid
                    resultsTable.DefaultView.Sort = "name";
dgResults.DataSource = resultsTable.DefaultView;
dgResults.DataBind();
if(resultsTable.Rows.Count < 1)
dgResults.Visible = false;
Label lblNoResults = new Label();
lblNoResults.Text = "The current search '" + Request.QueryString["TextName"] + "' returned 0 results.";
                         resultsCell.Controls.Add(lblNoResults);
resultsCell.Width = "100%";
resultsCell.Align = "center";
                         resultsCell.Style.Add("padding-top","5px");
