Finding out how many words are in the text input of JTextField

seems to work fine For small piece of text like that one in an inputText you could use split to generate a string array with the string break into words and so read the array's length:
code :
String test = "um dois      tres quatro        cinco ";
String [] splitted = test.trim().split("\\p{javaSpaceChar}{1,}");
System.out.println(splitted.length);
String inputText = input.getText();
String [] splitted = inputText.trim().split("\\p{javaSpaceChar}{1,}");
int numberOfWords = splitted.length;

I hope this helps you . JTextField.getCaretPosition()
JTextField.setCaretPosition(int pos)

Finding all occurrences of certain words from user text input using regex

I wish did fix the issue. Why not just use String#split and Array#count?.
Count of search terms found:
code :
story        = 'A long foo ago, in a bar baz, baz away...'
search_terms = ['foo', 'bar', 'baz']
search_terms.count { |search_term| story.split(/\W+/).include? search_term }
  # => 3
story        = 'A long foo ago, in a bar baz, baz away...'
search_terms = ['foo', 'bar', 'baz']
story.split(/\W+/).count { |word| search_terms.include? word }
  # => 4

Finding exact words in text, excluding quoted words

With these it helps First, we'll use a function to escape the characters of the word, just in case there's some that have special meaning for regexp.
code :
// from https://stackoverflow.com/a/30851002/240443
function regExpEscape(literal_string) {
    return literal_string.replace(/[-[\]{}()*+!<=:?.\/\\^$|#\s,]/g, '\\$&');
}
let text = 'word1, word2, word22, "word3" and word4';
let words = [ 'word1', 'word2', 'word3' , 'word4' ];
let regexp = new RegExp(words.map(word =>
'\\b' + regExpEscape(word) + '\\b(?=(?:[^"]*"[^"]*")*[^"]*$)').join('|'), 'g')

text.match(regexp)
// => word1, word2, word4

while ((m = regexp.exec(text))) {
  console.log(m[0], m.index);
}
// word1 0
// word2 7
// word4 34
let regexp = new RegExp(
  '\\b(?:' + 
  words.map(regExpEscape).join('|') + 
  ')\\b(?=(?:[^"]*"[^"]*")*[^"]*$)', 'g')

Python: Finding words using text file that matches string input without whitespace

This might help you You can use re.findall with an alternation pattern that includes all the words in words.txt:
code :
import re
def filesearch(userstring):
    print('\n'.join(re.findall('|'.join(map(str.rstrip, open("words.txt"))), userstring, re.IGNORECASE)))
