Lucene Keyword Search Released on the RCSB PDB Web SiteAfter 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 search results. 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. |
