Well, you could explore normalizing your table, particularly if many
of your 98 columns are null most of the time. Another option would be
to implement hstore for attributes and index with GIN/GIST --
especially if you need to filter on multiple columns. Organizing big
data for fast searching is a complicated topic and requires
significant thought in terms of optimization.
