The comma-delimited list shouldn't stop a properly written query. However, it does complicate things a bit.
Since the db isn't normalized, you could specify the position in the field at which the search term is located (position at beginning, end, entire field, anywhere in field), or just do it the easy way and bracket the search term with asterisks (search for *2005*, for example).
In re converting Access db to OpenOffice db, try exporting the Access db to a delimited text file. Create the db in OOo Base, then import the text file to fill the Base db.
A word of caution: since you have a field with comma-delimited values, use some other delimiter in the exported text file, such as forward or backward slash, hyphen, anything other than comma.
