5.6 Implementing Custom Search

Custom search applications can use the full power of Apache Solr through Solr's Java API SolrJ. Please see the documentation of Apache Solr and its SolrJ API for details.

There are just a few things to keep in mind when implement search for content beans:

  • Feeder applications such as the CAE Feeder and the Content Feeder require separate Apache Solr collections. When searching you must always specify the collection name, for example as parameter of the SolrJ method org.apache.solr.client.solrj.SolrClient#query.

  • Successfully indexed documents carry the value SUCCESS in the index field feederstate. To avoid finding placeholder index documents for feeding errors or internal index documents, you should always add a feederstate:SUCCESS filter query to your queries.

You can restrict the number of returned fields in a search result by setting the Solr fl (field list) parameter. In a CAE application you generally just need the content bean id, which is stored in field id. You can use IDs of the search results to get the Content Bean objects back from the CAE using an IdScheme or IdProvider. See the Content Application Developer Manual for details on Content Beans and their IDs.
