  expunge_deletes = FALSE,
  wait_searcher = TRUE,

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

# NOT RUN {
# start Solr: bin/solr start -f -c -p 8983

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

# create a collection
if (!conn$collection_exists("books")) {
  conn$collection_create(name = "books", numShards = 2)
}

# Add documents
file <- system.file("examples", "books.xml", package = "solrium")
cat(readLines(file), sep = "\n")
conn$update_xml(file, "books")

# Update commands - can include many varying commands
## Add files
file <- system.file("examples", "books2_delete.xml", package = "solrium")
cat(readLines(file), sep = "\n")
conn$update_xml(file, "books")

## Delete files
file <- system.file("examples", "updatecommands_delete.xml",
package = "solrium")
cat(readLines(file), sep = "\n")
conn$update_xml(file, "books")

## Add and delete in the same document
## Add a document first, that we can later delete
ss <- list(list(id = 456, name = "cat"))
conn$add(ss, "books")
## Now add a new document, and delete the one we just made
file <- system.file("examples", "add_delete.xml", package = "solrium")
cat(readLines(file), sep = "\n")
conn$update_xml(file, "books")
