How to make a closed search in Google Docs? -

i have document need find text or word, each time run function selection has go next if word or text found. if @ end should take me top in circular way find option in notepad.

is there way it?

i know findtext(searchpattern, from) not understand how use it.

there several wrappers , classes in documentapp. work contents of file.

• class range
• class rangeelement
• class rangebuilder

it necessary understand responsible. in case code below should work fine:

function myfunctiondoc() {      // sets search pattern     var searchpattern = '29';      // works current document      var document = documentapp.getactivedocument();      // detects selection     var selection = document.getselection();      if (!selection) {         if (!document.getcursor()) return;         selection = document.setselection(document.newrange().addelement(document.getcursor().getelement()).build()).getselection();     }     selection = selection.getrangeelements()[0];      // searches     var currentdocument = findnext(document, searchpattern, selection, function(rangeelement) {         // callback body         var doc = this;         var rangebuilder = doc.newrange();         if (rangeelement) {             rangebuilder.addelement(rangeelement.getelement());         } else {             rangebuilder.addelement(doc.getbody().astext(), 0, 0);         }         return doc.setselection(rangebuilder.build());     }.bind(document));  }  // search engine implemented on body.findtext function findnext(document, searchpattern, from, callback) {     var body = document.getbody();     var rangeelement = body.findtext(searchpattern, from);     return callback(rangeelement); } 

it looks pattern. if body.findtext returns undefined sets on top of document.
