Mfg. Search Terms Seem Weird

Ok,  I got a 30 day test drive of Electrical to see if it will meet our needs.  Looks like there are a lot of parts we use that are not in the data base.  I'll see how hard/easy it is to include them but when searching the data base this seems weird to me.  There is a searc field called reference: but no coulmns of the data base called "reference"  It seems to search on the Part column but then why didn't they just call it "Part"?
