Hello all!
I already posted this question to Stackoverflow
(http://stackoverflow.com/questions/12027451/solr-net-query-argumentexception-in-windows-forms)
but as is, either my question is too specific or just too trivial. I
don't know. But maybe I'm just trying to put the cart before the horse.
I have a C# Windows Forms application up and running. It uses the
Lucene.Net Library with which I created a Lucen index (off of a
Postgres-database). There are some articles which have more than one
value, so I decided to take numeric fields into account and used them in
my application as:
| var valueField= new NumericField(internalname, Field.Store.YES, true);
valueField.SetDoubleValue(value);
doc.Add(valueField);
|
|I can open my Lucene index in Luke and see all those nice fields I
made, so there should be no problem with the index; plus: my application
searches and displays the result sets of the lucene index quite fine.|
||
So I thought about trying Solr and read that I could use the Lucene
index at hand - I just had to edit the schema.xml file from Solr, which
I did. For the numeric field variables of the Lucene index I read
somewhere that I have to use TrieFields, so I updated my schema.xml as
follows:
|<fieldType name="tdouble" class="solr.TrieDoubleField" precisionStep="0"
omitNorms="true" positionIncrementGap="0"/>
[...]
<field name="LuminaireId" type="string" indexed="true" stored="true"/>
<field name="LampCount" type="tdouble" multiValued="true" indexed="true" stored="true"
required="false"/>
[...]
|||
For those fields, which use the numeric field I had the TrieDoubleField
of Solr in mind and changed them. Firing up Solr on Tomcat and hitting
it with a search query as "LampCount:1" returned all the right
documents. But the xml-output always says:
|<arr name="LampCount">
<str>ERROR:SCHEMA-INDEX-MISMATCH,stringValue=1</str>
</arr>
|
This could be the problem why my C# application is not running properly
(using the solrnet library as the brigde between Solr instance and
application) and always throws an ArgumentException when hitting my
solrnet implementation with:
| var results= solr.Query("LampCount:1");
|
But first things first: I'm not sure why there is this Index-Mismatch
and how to solve it -maybe I just didn't understand the explanation of
TrieFields or the port from NumericFields?
Any help would be greatly appreciated. :)
