Find in Blueprints search does not work with ":" or "=" symbols.

When adding comments to Blueprints with ":" or "=" symbols at the end of the comment results in searches not working. Searching for "todo:" will not work but removing the ":" results in a successful search.

1. Create a new blank project.
2. Add an Actor BP.
3. Place a comment into the graph (tested with "todo:")
4. Use find in blueprint search.
5. Search for "todo:"
6. It will not show up.
7. Change the colon to "=" should look like "todo=" now.
8. Search for "todo=" this will also not show up.
9. remove the "=" and search for just "todo" this will work.

Result: searching for anything within blueprints while putting a ":" or "=" at the end results in the search not working.

Desired effect: If a comment has a colon or any other symbol it should still show up when searching.

Also tested using a semicolon and that worked fine, it just seems to be regular colon and equal symbols not working.
