R: Update documents with JSON data

update_json {solrium} | R Documentation

## Update documents with JSON data

### Description

Update documents with JSON data

### Usage

    update_json(conn, files, name, commit = TRUE, optimize = FALSE,
      max_segments = 1, expunge_deletes = FALSE, wait_searcher = TRUE,
      soft_commit = FALSE, prepare_commit = NULL, wt = "json", raw = FALSE,
      ...)

### Arguments

`conn` | A solrium connection object, see SolrClient
`files` | Path to a single file to load into Solr
`name` | (character) Name of the core or collection
`commit` | (logical) If `TRUE`, documents immediately searchable. Deafult: `TRUE`
`optimize` | Should index optimization be performed before the method returns. Default: `FALSE`
`max_segments` | optimizes down to at most this number of segments. Default: 1
`expunge_deletes` | merge segments with deletes away. Default: `FALSE`
`wait_searcher` | block until a new searcher is opened and registered as the main query searcher, making the changes visible. Default: `TRUE`
`soft_commit` | perform a soft commit - this will refresh the 'view' of the index in a more performant manner, but without "on-disk" guarantees. Default: `FALSE`
`prepare_commit` | The prepareCommit command is an expert-level API that calls Lucene's IndexWriter.prepareCommit(). Not passed by default
`wt` | (character) One of json (default) or xml. If json, uses `fromJSON` to parse. If xml, uses `read_xml` to parse
`raw` | (logical) If `TRUE`, returns raw data in format specified by `wt` param
`...` | curl options passed on to `HttpClient`

### Details

You likely may not be able to run this function against many public Solr services, but should work locally.

    # connect
    (conn <- SolrClient$new())

    # Add documents
    file <- system.file("examples", "books2.json", package = "solrium")
    cat(readLines(file), sep = "\n")
    conn$update_json(files = file, name = "books")
    update_json(conn, files = file, name = "books")

    # Update commands - can include many varying commands
    ## Add file
    file <- system.file("examples", "updatecommands_add.json",
      package = "solrium")

    file <- system.file("examples", "updatecommands_delete.json",
      package = "solrium")
    cat(readLines(file), sep = "\n")
    conn$update_json(file, "books")

    # Add and delete in the same document

    ss <- list(list(id = 456, name = "cat"))
    conn$add(ss, "books")
