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
