Spotlight Crashes Often - Despite Rebuilding Search Index

Lately, when I begin to type into the Spotlight Search field, It goes away/crashes. Sometimes the actual spotlight icon disappears from my Menu Bar for several seconds. It does this often when I hit the space bar. As I start to type my 2nd word. Other times, just in the middle of typing my 1st word.

I tried rebuilding the search index a few times. No help.

I looked at Console System log right after a crash & this is what it listed:

Several minutes later, Spotlight crashed many times in a row as I kept trying to call up my “Apple Forum” folder.

This is what was listed:
