Full text search

Source: R/search_fulltext.R

Performs a search across all objects, and selects the closest matches. Generally, the user will provide the search term via the query parameter, with optional filtering via fq.

search_fulltext(
  query,
  fq = "idxtype:TAXON",
  output_format = "simple",
  start,
  page_size,
  sort_by,
  sort_dir
)

Arguments

query

string: the search term
fq

string: (optional) character string or vector of strings, specifying filters to be applied to the original query. These are of the form "INDEXEDFIELD:VALUE" e.g. "rk_kingdom:Fungi". See sbdi_fields("general") for all the fields that are queryable. NOTE that fq matches are case-sensitive, but sometimes the entries in the fields are not consistent in terms of case (e.g. kingdom names "Fungi" and "Plantae" but "ANIMALIA"). fq matches are ANDed by default (e.g. c("field1:abc","field2:def") will match records that have field1 value "abc" and field2 value "def"). To obtain OR behaviour, use the form c("field1:abc OR field2:def")
output_format

string: controls the print method for the "data" component of the returned object. Either "complete" (the complete data structure is displayed), or "simple" (a simplified version is displayed). Note that the complete data structure exists in both cases: this option only controls what is displayed when the object is printed to the console. The default output format is "simple"
start

numeric: (optional) (positive integer) start offset for the results
page_size

numeric: (optional) (positive integer) maximum number of records to return. Defaults to the server-side value - currently 10
sort_by

string: (optional) field to sort on. See sbdi_fields("general") for valid field names
sort_dir

string: (optional) sort direction, either "asc" or "desc"

Value

a named list with the components "meta" (search metadata), "facets" (search facet results), and "data" (the search results, in the form of a data frame). The contents (column names) of the data frame will vary depending on the details of the search and the results, but should contain at least the columns guid, name, commonName, rank, author, and occurrenceCount.
