Re: DataImportHandler: Partial Delete and Update (Hacking "deleteQuery" in SOLR 1.3?)

[Chantal Ackermann]

Hi again,

1.4 runs fine for me, now, but I'm still struggling for the correct 
delete query. There is few to no documentation at all for the new 
special commands, and I have problems guessing the correct setup from 
reading through the code. SORL-1060 is not enough help.

I've come up with a separate entity for issueing the deletes - is that 
how it should be done? How can I make sure that these deletes are issued 
before the other entities are processed? Is it enough to put it as first 
entity in the config?

<entity name="delete_from_index" pk="GROUPID"
        query="select GROUPID from DEFINITION
        where LANGUAGE='de'
                and CHANGED_DATE > '${dataimporter.last_index_time}'">
        <field column="$deleteDocByQuery"
                query="groupid:${delete_from_index.GROUPID}"/>
</entity>

I am not sure about which attributes to use for the "field" element when 
using that special command. I've put the query in with attribute "query" 
which is probably not right because I just wrote it down like that. 
Should I use the "name" attribute as done for the regular fields? Do I 
need to add a $skipDoc command (like it's mentioned in SOLR-1060)?

Thanks!
Chantal

Thanks, Paul! :-)

The wiki doesn't mark $deleteDocByQuery (and the other special commands)
as 1.4, as it usually does. Maybe it's worth correcting that?

$deleteDocByQuery is what you need .
