Ryan McKinley commented on LUCENE-4644:
---------------------------------------

Take a look at the definitions on:
http://docs.geoserver.org/latest/en/user/filter/ecql_reference.html#filter-ecql-reference

Is "some within" the CROSSES operation?  "some but not all interior points in 
common"

-----

It sounds like your bigger question is how to treat multi-valued fields in 
general.  Are they:
1. each field evaluated individually
2. treated as a single composite shape

Is there a difference between:
{code:xml}
<doc>
  <field name="f">POINT( a b )</field>
  <field name="f">POINT( c d )</field>
</doc>
{code}
and:
{code:xml}
<doc>
  <field name="f">MULTIPOINT( a b, c d )</field>
</doc>
{code}
