Example Configuration
| Code Block | ||
|---|---|---|

<application config="com.searchtechnologies.aspire:app-publish-to-gsa">
<properties>
<SolrNoUrl>true</SolrNoUrl>
<SolrHost>localhost</SolrHost>
<SolrPort>8983</SolrPort>
<aspireToSolrXsl>${appbundle.home}/config/xsl/aspireToSolr.xsl</aspireToSolrXsl>
<debug>false</debug>
</properties>
</application> |
| Note |
|---|
Any optional properties can be removed from the configuration to use the default value described on the table above. |
Edit Xsl
The default XSL transformation file can be found in AspireToSolr.xsl.
The default transformation XSL file provided by the publisher expects metadata as described in Connector AspireObject Metadata.
Add metadata field
To add a new metadata field extracted by an Aspire Connector add an XSL element under the <doc> tag.
| Code Block | ||
|---|---|---|
| ||
<field name="metafieldNameInSolr_t"> <xsl:value-of select="metafieldNameFromAspireObject" /> </field> |
Notice that the dynamic field _t is being used by default. If you have a Solr schema that supports your field, then just enter the field name as defined in the schema.
Change the document ID
The id of a Solr document is used to uniquely identify a file in the index. By default, Publish To Solr will use the following fields from the Aspire document in order of precedency (if one is missing, then the next will be used):
- fetchUrl
- url
- displayUrl
- id
If you want to change this behavior, edit or create a new XSL file which has the following element:
| Code Block |
|---|
<field name="id"> <xsl:value-of select="idFieldNameFromAspireObject" /> </field> |
Advanced Edit
More advanced changes can be accomplished reading the Solr Update XML Messages wiki.
