Solr Accessor for F#

⚠️ This is an alpha version! At this point no authentication is supported and there is not a lot of HTTP connection settings missing.

Client

To create a new Solr client instance, simply provide the base url endpoint:

open FSharp.Solr

let client = Client("http://localhost:8983/solr/")

The client class implements FSharp.Solr.IClient if any dependency injection is needed.

Search

In order to search the Solr collection a FSharp.Solr.Query.t needs to be created. This is a simple record, which can be build via a query builder

let query =
    Query.New
    |> Query.Query "*:*"                    // fills in the `q` parameter, alias: Query.Q, 
    |> Query.Filter "someField:someValue"   // fills in the `fq` parameter, alias: Query.Fq,
    |> Query.Field "someFieldName"          // fills in the `fl` parameter, alias: Query.Fl,
    |> Query.Rows 10u                       // fils in the `rows` parameter
    |> QUery.Custom "key" "value"           // adds a key=value to the query

let result = client.Search(query, Async.DefaultCancellationToken)        // return a Task<ClientResult>
let result = client.SearchAsync(query, Async.DefaultCancellationToken)   // return a Async<ClientResult>

The return value of client.Search() is a ClientResult, defined as Result<QueryResult, ClientError>. In case of a success, a QueryResult is returned, which is (at this point) defined as

type QueryResult = {
    Raw: string;    // raw respone returned by SOLR
}

In case of an error, a ClientError record is returned. This record is defined as

type ClientError = {
    Status: HttpStatusCode;     // HTTP status code
    Message: string;            // HTTP response content
}
