Solr 1.4: filter documens using fields

[Rui António da Cruz Pereira <ru...@gmail.com>]

Hi all!
I'm using StandardRequestHandler and I wanted to filter results by two 
fields in order to avoid duplicate results (in this case the documents 
are very similar, with differences in fields that are not returned in a 
query response).
For example, considering the response:

<doc>
    <long name="instancekey">285</long>
    <str name="instancename">186_Testing</str>
    <long name="topologyid">3142</long>
    <str name="topologyname">Locais</str>
</doc>
<doc>
    <long name="instancekey">285</long>
    <str name="instancename">186_Testing</str>
    <long name="topologyid">3141</long>
    <str name="topologyname">inventario</str>
</doc>
<doc>
    <long name="instancekey">285</long>
    <str name="instancename">186_Testing</str>
    <long name="topologyid">3141</long>
    <str name="topologyname">inventario</str>
</doc>
<doc>
    <long name="instancekey">285</long>
    <str name="instancename">186_Testing</str>
    <long name="topologyid">3140</long>
    <str name="topologyname">CPE</str>
</doc>
<doc>
    <long name="instancekey">285</long>
    <str name="instancename">186_Testing</str>
    <long name="topologyid">3140</long>
    <str name="topologyname">CPE</str>
</doc>

I wanted to filter by: instancekey and topologyid in order to get the 
following response:
<doc>
    <long name="instancekey">285</long>
    <str name="instancename">186_Testing</str>
    <long name="topologyid">3142</long>
    <str name="topologyname">Locais</str>
</doc>
<doc>
    <long name="instancekey">285</long>
    <str name="instancename">186_Testing</str>
    <long name="topologyid">3141</long>
    <str name="topologyname">inventario</str>
</doc>
<doc>
    <long name="instancekey">285</long>
    <str name="instancename">186_Testing</str>
    <long name="topologyid">3140</long>
    <str name="topologyname">CPE</str>
</doc>

I'm manage to do the filtering in the client, but then the paging 
doesn't work as it should (some pages may contain more duplicated 
results than others).
Is there a way (query or other RequestHandler) to do this?

Thanks,
    Rui Pereira

not at the moment, but some people have been working on trying to solve 
the broader problem in an efficient way...
