Distributed Search Features

Distributed search sub-parameters, to be specified as a hash array:

Parameter	Type	Description
shards	array	Solr shards/cores to search as identified by their identifier in solr.ini
searchfields	array	Fields to search across the specified shards
returnfields	array	Fields to return across
rawfilterlist	array	Array of filter expressions which are combined with a boolean 'OR'. The combined expression is then also combined with a boolean 'OR' along the other filter queries (explicit or originating from the Exponential permissions)

Important: The use of distributed_search requires also the 'asObjects' parameter set to false()

For best relevancy, the respective solr schema's in schema.xml needs to be "tuned" for distributed search in order to function properly with respect to relevance. Best practice is to use <copyField> directives to aggregate fields together with a common field name.

Example: Using the eZ Find aggregate field created by default for Exponential search indexes: ezf_def_text

Facets can be specified in the main facets parameter, by using the Raw Solr Field Identifiers used by the foreign search indexes.
