Find words which contains more than 3 e vowels is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.
Task

Use the dictionary   unixdict.txt

Phix

<lang Phix>function note(string word) return find_any("aiou",word)=0 and length(find_all('e',word))>3 end function sequence notes = filter(get_text("demo/unixdict.txt",GT_LF_STRIPPED),note) printf(1,"%d words: %s\n",{length(notes),join(shorten(notes,"",3))})</lang>

Output:
16 words: belvedere dereference elsewhere ... seventeenth telemeter tennessee

REXX

This REXX version doesn't care what order the words in the dictionary are in,   nor does it care what
case  (lower/upper/mixed)  the words are in,   the search for the words and vowels is   caseless.

It also allows the vowel to be specified,   and also the minimum number of the specific vowels to be specified on the command line (CL) as well as the dictionary file identifier. <lang rexx>/*REXX pgm finds words (within an identified dict.) which contain more than three "e"s.*/ parse arg char many iFID . /*obtain optional arguments from the CL*/ if char== | char=="," then char= 'e' /*Not specified? Then use the default.*/ if many== | many=="," then many= 4 /* " " " " " " */ if iFID== | iFID=="," then iFID='unixdict.txt' /* " " " " " " */ chrU= char; upper chrU /*obtain an uppercase version of char.*/ 

          do #=1  while lines(iFID)\==0         /*read each word in the file  (word=X).*/
          x= strip( linein( iFID) )             /*pick off a word from the input line. */
          @.#= x                                /*save:  the original case of the word.*/
          end   /*#*/                           /* [↑]   semaphore name is uppercased. */
  1. = # - 1 /*adjust word count because of DO loop.*/

say copies('─', 30) # "words in the dictionary file: " iFID finds= 0 /*count of the "eeee" words found. */ vowels= 'aeiou' /*obtain the list of all the vowels. */ upper vowels /*uppercase all the other vowels. */ vowels= space( translate(vowels, , chrU), 0) /*elide the one vowel we're looking for*/ 

    do j=1  for #;      $= @.j                  /*process all the words that were found*/
    upper $                                     /*uppercase it for caseless finds.     */
    if verify(vowels, $, 'M')>0  then iterate   /*Does it contain other vowels? Skip it*/
    if countstr(chrU, $) < many  then iterate   /*Does it have enough of  'e's?   "   "*/
    finds= finds + 1                            /*bump count of only "e" vowels found. */
    say right(left(@.j, 30), 40)                /*indent original word for readability.*/
    end        /*j*/
                                                /*stick a fork in it,  we're all done. */

say copies('─', 30) finds ' "e" words found using the characters: ' many "'e'"</lang>

output   when using the default inputs:
