have a question about the <span class=SpellE>zcatalog</span>. I have a directory
filled with nearly 6000 <span class=SpellE>Plone</span> folders. Each of these
folders holds information about a business in my town and they are contained in
a <span class=SpellE>zcatalog</span>. The problem is that a search generally
takes about 50 seconds. A search for a business can be done by Business
Category, Business Type, Location, Keywords or a combination of any of these. The
business category and business type are both keyword indexes, the location is a
field index and the keywords is a text index. Results are sorted by a <span
class=SpellE>searchValue</span> which is a field index. The query is shown
below:<o:p></o:p></span></font></p>
