Apache Solr Reference Guide Covering Apache Solr 6.0

Although the stats.facet parameter is no longer recommended, sets of stats.field parameters can be
referenced by ' tag' when using Pivot Faceting to compute multiple statistics at every level (i.e.: field) in the tree
of pivot constraints.
For more information and a detailed example, please see Combining Stats Component With Pivots.
The Query Elevation Component
The Query Elevation Component lets you configure the top results for a given query regardless of the normal
Lucene scoring. This is sometimes called "sponsored search," "editorial boosting," or "best bets." This
component matches the user query text to a configured map of top results. The text can be any string or
non-string IDs, as long as it's indexed. Although this component will work with any QueryParser, it makes the
most sense to use with DisMax or eDisMax.
The Query Elevation Component is supported by distributed searching.
All of the sample configuration and queries used in this section assume you are running Solr's " techproducts"
example:
bin/solr -e techproducts
Configuring the Query Elevation Component
You can configure the Query Elevation Component in the solrconfig.xml file.
string
elevate.xml
explicit
elevator
Optionally, in the Query Elevation Component configuration you can also specify the following to distinguish
editorial results from "normal" results:
foo
The Query Elevation Search Component takes the following arguments:
Argument
queryFieldType
Description
Specifies which fieldType should be used to analyze the incoming text. For example, it
may be appropriate to use a fieldType with a LowerCaseFilter.
