OSD records are searched with the PostgreSQL fulltext indexing and query system (syntax details). Each search field (except for the "brief narrative" and MLRA) corresponds with a section header in an OSD. The results may not include every OSD due to formatting errors and typos. Results are scored based on the number of times search terms match words in associated sections.
OSDquery( everything = NULL, mlra = "", taxonomic_class = "", typical_pedon = "", brief_narrative = "", ric = "", use_and_veg = "", competing_series = "", geog_location = "", geog_assoc_soils = "" )
search entire OSD text (default is NULL),
mlra may also be specified, all other arguments are ignored
a comma-delimited string of MLRA to search ('17,18,22A')
search family level classification
search typical pedon section
search brief narrative
search range in characteristics section
search use and vegetation section
search competing series section
search geographic setting section
search geographically associated soils section
data.frame object containing soil series names that match patterns supplied as arguments.
See this webpage for more information.
family level taxa are derived from SC database, not parsed OSD records
MLRA are derived via spatial intersection (SSURGO x MLRA polygons)
MLRA-filtering is only possible for series used in the current SSURGO snapshot (component name)
logical AND: &
logical OR: |
wildcard, e.g. rhy-something rhy:*
search terms with spaces need doubled single quotes: ''san joaquin''
combine search terms into a single expression: (grano:* | granite)
