It return no matches in such a case.\r\n\r\nHere is a script which demonstrates the problem, when the script is executed to act upon its own code as input data in the active editor tab in N++:\r\n\r\n```py\r\n# -*- coding: utf-8 -*-\r\nfrom __future__ import print_function\r\n\r\nfrom Npp import *\r\n\r\npos1 = 0; pos2 = editor.getLength()  # forward search, i.e., pos1 \u003c pos2\r\n(pos1, pos2) = (pos2, pos1)  # swap to do backward search\r\n\r\nmatches = []\r\neditor.research('a', lambda m: matches.append(m.span(0)), 0, pos1, pos2)\r\nprint('research:', matches[0]) if len(matches) > 0 else print('research: no matches')\r\n\r\n# show that editor.findText() works fine either forward or backward:\r\nft_pos_tup = editor.findText(FINDOPTION.REGEXP, pos1, pos2, 'a')\r\nprint('ft_pos_tup:|{T}|'.format(T=ft_pos_tup))\r\n```\r\n\r\nTo see the problem, run the script as written.  To see that the script logic works for a forward search, comment out the \"swap\" line.  Note that a call to `editor.findText()` is included to show that it works correctly for either backward or forward searches.","author":{"url":"https://github.com/alankilborn","@type":"Person","name":"alankilborn"},"datePublished":"2024-01-23T16:11:29Z","url":"https://github.com/bruderstein/PythonScript/issues/323"}
