ITIS Solr interface

There are four methods.

• itis_search() - Search
• itis_group() - Group
• itis_highlight() - Hightlight
• itis_facet() - Facet

These four methods use the equivalent functions in the package solrium, e.g., ritis::itis_search() uses solrium::solr_search(), etc. The itis_*() functions simply use ... to allow users to pass on parameters to the wrapped solrium functions. So do read the solrium docs.

Some examples:

matches only monomials

itis_search(q = "nameWOInd:/[A-Za-z0-9]*[ ]{0,0}*/")

matches only binomials

itis_search(q = "nameWOInd:/[A-Za-z0-9]*[ ]{1,1}[A-Za-z0-9]*/")
