Custom queries can be added to any file the vivo-home/rdf/display/everytime directory (or any other file directory read by VIVO during startup). Using searchIndexerConfigurationVivo.n3 as a template, create a query that returns the data you wish to add to the search index. For example, if you wanted to create a custom search field for tracking open access publications you flag with a custom data property:

Code Block
@prefix : <http://vitro.mannlib.cornell.edu/ns/vitro/ApplicationSetup#> .
@prefix rdfs:  <http://www.w3.org/2000/01/rdf-schema#> .

    a   <java:edu.cornell.mannlib.vitro.webapp.searchindex.documentBuilding.SelectQueryDocumentModifier> ,
        <java:edu.cornell.mannlib.vitro.webapp.searchindex.documentBuilding.DocumentModifier> ;
    rdfs:label "open access" ;
    :hasTargetField "open_access_s" ;
    :hasSelectQuery """
        PREFIX wos: <http://webofscience.com/ontology/wos#>
        SELECT ?status
        WHERE {
            ?uri wos:openAccess ?status .
        }
        LIMIT 1
        """ .
