For Each filePath In fileList
Assign fileContent = File.ReadAllText(filePath)

For Each searchText In textsToFind
    // Search for the current text within the file content
    If fileContent.Contains(searchText)
    Then
        // Increment the fileCount when the condition is met
        Assign fileCount = fileCount + 1

        Assign words = fileContent.Split({" "}, StringSplitOptions.RemoveEmptyEntries)
        
        // Find the index of the search text

        For i = Math.Max(0, searchTextIndex - 2) To Math.Min(words.Length - 1, searchTextIndex + 2)
            wordsBeforeAndAfter.Add(words(i))
        Next
