Hi All,
We're running Solr 3.4 (I know, I know - we have another project to upgrade
this) and we have a fieldtype defined with an externalFileField as:
<fieldtype name="filectr" keyField="id" defVal="1" stored="true"
indexed="false" class="solr.ExternalFileField" valType="float"/>
(Actually, I have tried this with both `stored="true"` and
`stored="false"`).
The field using this fieldtype is defined as:
<field name="ctr" type="filectr" indexed="false" stored="true"
required="false"/>
We're successfully using this in our boost function to alter the rankings
based on click through rates (ctr).
Now we'd like to return this value so we can tag popular documents from our
index.
I have tried various combinations from examples I've found in
Stackoverflow, the mailing list archives and so on.
For example:
fl=ctr
fl=field(ctr)
fl=ctr:field(ctr)
None of these have returned a ctr field with the document. As part of the
queries I've been testing, I have ensured to filter on documents that
definitely have a value in our external file. I have also tried re-indexing
the documents as this was mentioned in a few places but it makes no
difference (which kind of makes sense to me as the whole point is that this
is an external field).
Now, I found an old copy of the manual for 3.4 where it states about
externalFileFields that:
> External fields are not searchable. They can be used only for function
queries
Whereas, in the newer versions of the docs it states "they can be used for
function queries and display".
Does this mean it's simply not possible in Solr 3.4 or am I just doing
something wrong?
Thanks in advance,
Adam
