After a period of beta testing, the Lucene keyword search engine
has replaced the previously-used LDAP keyword search engine to
support text searches on the RCSB PDB home page, SearchLite, and
the "Text Search" field on SearchFields. Lucene uses an index of
the remediated mmCIF files to return much more accurate keyword
Lucene supports wildcard searches, phrases, Boolean queries, and
offers a spell checker. Options are offered to narrow the scope
of the query, for example, to search for author names or PDB IDs;
the default is set to search the entire text of the mmCIF file
indices. Additionally, partial word and exact word matches are
supported; the default is set to perform an exact word match,
unless the partial word match option is selected. The home page
keyword search will locate exact word matches to a query.
Examples of supported queries can be found on the SearchLite page at www.rcsb.org/pdb/searchlite.html, and additional help can be found at www.rcsb.org/pdb/help-searchlite.html.
