Description

Add documents from R objects

Usage

add(
  x,
  conn,
  name,
  commit = TRUE,
  commit_within = NULL,
  overwrite = TRUE,
  boost = NULL,
  wt = "json",
  raw = FALSE,
  ...
)

Arguments

x	Documents, either as rows in a data.frame, or a list.
conn	A solrium connection object, see SolrClient
name	(character) A collection or core name. Required.
commit	(logical) If TRUE, documents immediately searchable. Default: TRUE
commit_within	(numeric) Milliseconds to commit the change, the document will be added within that time. Default: NULL
overwrite	(logical) Overwrite documents with matching keys. Default: TRUE
boost	(numeric) Boost factor. Default: NULL
wt	(character) One of json (default) or xml. If json, uses jsonlite::fromJSON() to parse. If xml, uses xml2::read_xml() to parse
raw	(logical) If TRUE, returns raw data in format specified by wt param
...	curl options passed on to crul::HttpClient

Details

Works for Collections as well as Cores (in SolrCloud and Standalone modes, respectively)

Examples

## Not run: 
(conn <- SolrClient$new())

# create the boooks collection
if (!collection_exists(conn, "books")) {
  collection_create(conn, name = "books", numShards = 1)
}

# Documents in a list
ss <- list(list(id = 1, price = 100), list(id = 2, price = 500))
add(ss, conn, name = "books")
conn$get(c(1, 2), "books")

# Documents in a data.frame
## Simple example
df <- data.frame(id = c(67, 68), price = c(1000, 500000000))
add(df, conn, "books")
df <- data.frame(id = c(77, 78), price = c(1, 2.40))
add(df, conn, "books")

## More complex example, get file from package examples
# start Solr in Schemaless mode first: bin/solr start -e schemaless
file <- system.file("examples", "books.csv", package = "solrium")
x <- read.csv(file, stringsAsFactors = FALSE)
class(x)
head(x)
if (!collection_exists(conn, "mybooks")) {
  collection_create(conn, name = "mybooks", numShards = 2)
}
add(x, conn, "mybooks")

# Use modifiers
add(x, conn, "mybooks", commit_within = 5000)

# Get back XML instead of a list
ss <- list(list(id = 1, price = 100), list(id = 2, price = 500))
# parsed XML
add(ss, conn, name = "books", wt = "xml")
# raw XML
add(ss, conn, name = "books", wt = "xml", raw = TRUE)
