The Lucene Query Search

SureChEMBL uses the Lucene QueryParser internally. Therefore, if you are comfortable writing a complex query with the Lucene syntax, you may do so using all available Lucene Query field names.

Note: See Lucene Query Parser Details for an extended explanation of writing search criteria using Lucene. See Lucene Query Field Names and Examples for a complete list of fields.
