A Boost Function can combine numeric values from the result document to produce a number which is either added or multiplied with the other boost value from the query result.
To see all available fields, see the <ahref="IndexSchema_p.html">YaCy Solr Schema</a> and look for numeric values (these are names with suffix '_i').
The Boost Query is attached to every query. Use this to statically boost specific content in the index.
Example: "fuzzy_signature_unique_b:true^100000.0f" means that documents, identified as 'double' are ranked very bad and appended to the end of all results (because the unique are ranked high).
This is the set of searchable fields. Entries without a boost value are not searched. Boost values make hits inside the corresponding field more important.
