searching for text and selecting in word

You can try using the .NET Document Viewer control from LEADTOOLS to load your Document files and search text. You can find more information about this control here:
https://www.leadtools.com/help/leadtools/v20/dh/doxui/documentviewer.html

After this, you can use the following code to search a specific text in the document after loading it into the Document Viewer control:

var text = _documentViewer.Text;
// Make sure we get the page text if necessary
text.AutoGetText = true;
// We will find all matches of "LEAD", ignoring the case
var options = new DocumentViewerFindText();
// The text
options.Text = "LEAD";
// Ignore case
options.MatchCase = false;
// Any word that contains the phrase
options.WholeWordsOnly = false;
// Find all results in the bounds, not just the first
options.FindAll = true;
// Highlight the results in the View
options.RenderResults = true;
// Optionally change the highlight color
//DocumentViewerText.FoundTextBrush = new SolidBrush(Color.FromArgb(52, Color.Brown));
options.SelectFirstResult = true;
options.Start = DocumentViewerFindTextStart.AfterSelection;
// If we were just looking for the first match, we could use "Loop" to loop around
// if we found nothing between the start position and the end bound.
//options.Loop = true;
// You will likely want to clear the previous highlighted results
// on the screen so only our new results will show.
text.ClearRenderedFoundText();
// Search
var results = text.Find(options);
int resultsCount = results != null ? results.Count : 0;
if (resultsCount > 0)
MessageBox.Show(string.Format("Found {0} results", resultsCount));
else
MessageBox.Show("No matches found.");

You can use Interop word class but quite slow or you can use openxml library
