Libre Office Writer search and replace locks up the program

[drfrank01]

I use this for daily adding to large documents of 1 2 even up to 700 pages,
When I tried to use the search function to find a particular part of the document the word processor locked up
I rebooted 2 times and recovered the documents but my changes had in fact been lost.

In continuing to use the program I notice after testing a stable loaded writer everything seems to work well but the search and replace function when searching actually finds the WRONG text string when it does not lock up.
