Query examples

  1. Search only the title field in the “docs” collection for the term “solr”, and format the results as JSON:
http://localhost:{api-port}/api/query-pipelines/default/collections/docs/select?q=solr&fl=title&wt=json
  1. Use the following query with wildcards and character escaping in the Query Workbench to search for both BLU RAY MOVIES and CAMERA classes in the VIDEO/CD and PHOTO/CAMERA departments:
    • class_s:*RA* AND department_s:*O\/C*
  2. Use a movie collection to select the movie ID and rating where the rating is equal to 4. 
http://FUSION_HOST:FUSION_PORT/api/query-pipelines/default/collections/docs/select?q=*:*&fl=movie_id,rating&fq=rating:4
  1. Search for movies with “black” in the title, starting at the 20th result for pagination, then return the results as XML:
http://FUSION_HOST:FUSION_PORT/api/query-pipelines/default/collections/docs/select?q=black&fl=title&start=20&rows=20&wt=xml
