Making _indexname parameter optional
Once Solr and Sitecore configurations are in place and external data is indexed, we can start querying data. By default each query that Sitecore makes to Solr includes _indexname filtering parameter, which makes cross-core querying a bit tricky. I had to extend Sitecore's SolrCompositeQuery to implement Solr query operator, grouping and highlighting which I've blogged about (here), so it only made sense to add ability to omit _indexname parameter from the query in the extension class. All I did I added a parameter to all my custom methods that indicates whether the index name should be included or not.
public class ExtendedCompositeQuery : SolrCompositeQuery
{
public ExtendedCompositeQuery(AbstractSolrQuery query, AbstractSolrQuery filterQuery, IEnumerable methods,
IEnumerable virtualFieldProcessors, IEnumerable facetQueries, QueryOptions options,
LocalParams localParams = null, bool filterByIndexName = true)
: base(query, filterQuery, methods, virtualFieldProcessors, facetQueries)
{
QueryOptions = options;
LocalParams = localParams;
FilterByIndexName = filterByIndexName;
}
public QueryOptions QueryOptions { get; set; }
public LocalParams LocalParams { get; set; }
public bool FilterByIndexName { get; set; }
}
In extended LinqToSolrIndex class I added a check for this parameter in Execute method.
That provided an ability to run cross-core queries if I needed to.
if (compositeQuery.FilterByIndexName)
{
options.AddFilterQueries(new SolrQueryByField("_indexname", context.Index.Name));
}
That provided an ability to run cross-core queries if I needed to.
Custom Index Multilist with Search field
Another featured that had to implemented is handpicking of netFORUM entities and linking to them. Since these entities only live in Solr index, I needed to provide a user friendly mechanism to pick and choose entities from index. To solve this problem I created a new Sitecore field that is almost exact duplicate of default "Multilist with Search", cleared the Control field and entered values into Assembly and Class fields that match with field extension class I created.
CustomIndexUISearchResultItem.cs
To make sure that queries from this new field take a different route than SitecoreUISearchResultItem and UISearchResult ones, I've implemented a new class called CustomIndexUISearchResultItem.
