    Solr query language

    This cheat sheet is a quick reference to the Solr query language. Use this syntax when querying Managed Fusion via the Query API.

    Additional information about Solr query syntax can be found in the Solr Query documentation.

    There are two ways to query a Managed Fusion collection using the parameters below:

    Wildcards

    Wildcards and regular expressions are supported.

    • ?

      Single-character wildcard

    • *

      Multi-character wildcard

    Escape characters

    Some characters in query fields must be escaped using a backslash \. Adding \ before the following includes them in the query as literal values:

    • ?

    • *

    • \

    • /

    • "

    Queries against facets are case sensitive.

    Common query parameters

    q

    Defines a query using standard query syntax. This parameter is mandatory.

    fq

    Filter query. A query string that limits the query results without influencing their scores.

    sort

    Sort field/direction. The field on which to sort, followed by a space and direction (desc or asc). You can specify multiple sort fields like this: sort=title asc,year desc.

    rows

    Max results per page. This sets the "page size" for paginated search results.

    start

    Pagination offset. The number of results to skip, for pagination purposes.

    fl

    Field List. The list of fields to return in the query results.

    df

    Default field. Used to configure the q and fq parameters. If not specified, the default field is text.

    wt

    Response writer. Select the response format by specifying one of Solr’s response writers.

    Query examples

    1. Search only the title field in the "docs" collection for the term "solr", and format the results as JSON:

    http://EXAMPLE_COMPANY.lucidworks.cloud/api/query-pipelines/default/collections/docs/select?q=solr&fl=title&wt=json
    Replace EXAMPLE_COMPANY with the name provided by your Lucidworks representative.

    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*

    1. 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
