Avanced search

Text search has 2 extra parameters in order to remove any usual words and/or words lower than a length.

You can enable these functionalities in __construct();

ex1. __construct($text, 3);           // remove words with <3 characters
ex2. __construct($text, null, 0.3);   // remove words with 30% of frequency
