"plant root green"
    This searchs for the words in the 
    concepts, title, and description 
    of the resource
    

If you want to limit the search to a 
particular field in the index, you can
specify that field as part of your 
query.  The syntax looking for concept 
nodes called "plant" would look like:
   "concepts:plant" or extended like:
   "concepts:plant root green"
Remember that if the word "plant" appears
in the description of the resource, the
above query will not retrieve it.

You can also combine searches in 
different fields:

  "concepts:plant links:"found in" image:x"

This query will look for concepts OR 
resources with "found in" links, OR
images.  Those with all three will be at the
top of the list found.  To make sure that 
all three search criteria are present in 
the returned search results, we modify the 
query to look like this:
 
  "+(concepts:plant) +(links:"found in") 
   +(image:x)"


Here are the list of fields that are 
currently being used in the index.


concepts:
links:
title:
desc:
keywords:
image:x
cmap:x
audio:x
text:x
movie:x
unknown:x


These fields tell how the resource is 
used, either including or included in 
another resource

resourceUsed:x
resourceNotUsed:x
usesResource:x

These fields will not generally be
useful for queries because they relate to 
internal ways the resources are stored.
