Hi All,

Hope you can help me with this one...

I have a filter on one of our marts (www.knockoutmouse.org, idcc_targ_rep 
dataset) configured as a multi-select like so:

---
    <FilterCollection displayName="Pipeline" internalName="pipeline">
      <FilterDescription displayName="Pipeline" displayType="list" 
field="pipeline" internalName="pipeline" key="id_1022_key" legal_qualifiers="=" 
multipleValues="1" qualifier="=" style="menu" tableConstraint="main" 
type="list">
        <Option displayName="KOMP-CSD" internalName="KOMP-CSD" 
isSelectable="true" value="KOMP-CSD"/>
        <Option displayName="KOMP-Regeneron" internalName="KOMP-Regeneron" 
isSelectable="true" value="KOMP-Regeneron"/>
        <Option displayName="EUCOMM" internalName="EUCOMM" isSelectable="true" 
value="EUCOMM"/>
        <Option displayName="NorCOMM" internalName="NorCOMM" 
isSelectable="true" value="NorCOMM"/>
        <Option displayName="mirKO" internalName="mirKO" isSelectable="true" 
value="mirKO"/>
      </FilterDescription>
    </FilterCollection>
---

But, it's producing unexpected results when you query for either of the 
pipelines separately, or together...

i.e. the following xml:

---
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE Query>
<Query  virtualSchemaName = "default" formatter = "CSV" header = "0" uniqueRows 
= "1" count = "" datasetConfigVersion = "0.6" >

  <Dataset name = "idcc_targ_rep" interface = "default" >
      <Filter name = "pipeline" value = "KOMP-CSD,EUCOMM"/>
      <Attribute name = "escell_clone" />
  </Dataset>
</Query>
---

retrieves 129816 rows of data, but when you do the different pipelines 
separately, they do not add up to this number...

KOMP-CSD on its own is 59440
EUCOMM on its own is 76076

So, combined they give 135516 rows of results - 5700 more than the first query!

The attribute i'm selecting ('escell_clone') is unique for every row in the 
database, so it's not that i'm getting duplicates for the separate queries.

Any ideas as to why i'm getting this shortfall in the first query?  Is there 
something wrong with the way I set up the filter?

Any help is much appreciated. :)

Thanks,

Daz
