[opencms-dev] Mapping OpenCMS structured content XML field to a SOLR field

[Arturo Martín Lladó]

Hi,

We are trying to map an OpenCMS structured content XML field to a SOLR
field in order to perform a search using that field as a filter.

The XML field is described this way in the XSD file:

<xsd:complexType name="OpenCmsContrato">
    <xsd:sequence>
    [...]
        <xsd:element name="numeroExpediente" type="OpenCmsString"
minOccurs="1" maxOccurs="1" />
    [...]
    </xsd:sequence>
    <xsd:attribute name="language" type="OpenCmsLocale" use="required"/>
</xsd:complexType>

And these are the search settings for the element, defined in the same XSD file:

<xsd:annotation>
    <xsd:appinfo>
    [...]
        <searchsettings>
            <searchsetting element="numeroExpediente" searchcontent="true">
                <solrfield targetfield="numexp" />
            </searchsetting>
        </searchsettings>
    [...]
    </xsd:appinfo>
</xsd:annotation>

The target SOLR field "numexp" is defined this way in SOLR's schema.xml file:

<fields>
    <field name="numexp"                 type="string"
indexed="true"  stored="true" />
    [...]
</fields>

And this is the way we perform the query to SOLR on a JSP file:

CmsSearchManager manager = OpenCms.getSearchManager();
CmsSolrIndex index = manager.getIndexSolr("Solr Online");

String query = "fq=type:contrato";

if (!"".equals(text))
    query += "&fq=numexp:" + text;

CmsSolrResultList listFiles = index.search(cmso, query);

When we execute this code, we get listFiles.size() = 0, but when we
change the filter field to the predifined SOLR field "content", this
way:

if (!"".equals(text))
    query += "&fq=content:" + text;

we get the expected result.

With the CmsSearchResource object we get using the "content" SOLR
field as filter, we are able to iterate over the fields of its inner
I_CmsSearchDocument, getting this list as result:

id
contentblob
path
type
suffix
created
lastmodified
contentdate
relased
expired
res_locales
con_locales
template_prop
default-file_prop
notification-interval_prop
NavPos_prop
enable-notification_prop
locale_prop
NavText_prop
Title_prop
category
ca_excerpt
timestamp
score
link

No presence of the "numexp" field on the list. Why? Are we missing any
step? Do we have to configure something else in order to make the
mapping work?

Thank you in advance.

Regards,

Arturo.
