How can I change field boosts

  1. Open C:\Bitnami\solr-8.3.0-0\apache-solr\server\solr\mpp_index\conf\solrconfig.xml
  2. Find /dp_select SearchHandler
  3. Specify boosts on fields in parameters such as qf param
    For example:
    part_number_search^1 universal_product_codes^0.7  vendor_part_numbers^0.7 cross_reference_parts^0.7  manufacturer_search^0.5 attr_search^0.5 description_search^0.4 vendor_descriptions^0.3  short_description^0.3 product_name^0.3 attributes^0.1 long_description^0.1 description_hl^0.01
  4. copy your changes to dp_suggest handler

How can I change the score of a document based on the value of a field (say, "hits_boost" or "velocity_boost")

div(sum(hits_boost,velocity_boost,ga_product_boost,ga_category_boost), 4)

For example:
Use a FunctionQuery as part of your query.

How can I boost results that have a field that matches a specific value.
