(finder.getString) problems

Hi, I’m working on a project that searches a website for words. Down below is my code, but i don’t know how a (finder.getString) works. I need this so that when he finds the words I’m looking for, a frequency generator will activate

The thing that doesn’t work is the finder.getString because I don’t know what you need to wright if you only what it to check for words and not data.

This is were the finder.getString needs to look for:

eenheden 0902600 Blusgroep Pannerden

and this is my code so far:

//http://www.112meldingen.nl/index.php

#include <SPI.h>
#include <Ethernet.h>
#include <TextFinder.h>

byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; //physical mac address
byte ip[] = { //my ip }; // ip in lan
byte gateway[] = { //my internet acces }; // internet access via router
byte subnet[] = { //my subnet mask }; //subnet mask

// Server 112meldingen
IPAddress server(213,152,170,26);

EthernetClient client;
TextFinder  finder( client ); 


void setup()
{
  Ethernet.begin(mac, ip);
  Serial.begin(9600);
  Serial.println("Setup...");
}

void loop()
{
  if (client.connect(server, 80))
  { 
    
    Serial.println("Connecting to 112meldingen...");
    client.println("GET /index.php HTTP/1.0");
    client.println("HOST:112meldingen.nl\n\n");
    client.println();
    Serial.println("Connected...");
  }
  else
  {
    Serial.println(" connection failed");
  }


  if (client.connected())
  {
   
    // eenheden
   if (finder.getString("eenheden, 0902600 Blusgroep pannerden"));
   { 
      Serial.print("found")
     
     //check gps en open gate
   }
  }
   else
   {
     Serial.print("No data found...");
      delay(2000);
  {
    Serial.println("Disconnected");
  }

  client.stop();
  client.flush();
  delay(10000);
} }

TextFinder.h is now kinda obsolete, find features are now embeddedin the Stream class.
