  • Advanced Search Query Basics
  • Targetable Fields Index for Judicial Opinions Cases

All case libraries in CasePortal use a single search field to support simple keyword searches and advanced search queries (using Lucene Query Syntax).

In this document you will find instructions for how to build advanced search queries and which specific fields are targetable.

What I want to do How I do it Example
Apply different operators to different groups of terms Group terms together using brackets () and operators (AND or OR) (google OR alphabet) AND (samsung OR sony)
Create a complex query Combine the functions above "class action" AND def:(Google OR "Alphabet Inc.") AND plaint:(Samsung* or Apple~)
Exclude certain keywords or phrases Apply the NOT operator def:Apple AND NOT def:"Apple Inc."
Search for one term or another Apply the OR operator. This is the default operator. google OR apple will return matches with either google or apple or both
Search for one term and another Apply the AND operator google AND alphabet will only return matches with both
Search using a phrase Add quotations around the phrase (") "google inc." will only return results that match the complete phrase
Search for variable endings of a root word Apply a wildcard using asterisk (*) educat* will match educate, educated, educating, education, and so on
Search for words with possible misspellings or variations Apply the fuzzyness operator (~) rise~ will match risk, rising, risen, rose, and so on
Search for words that are close together (“proximity search”) Use the tilde (~) symbol at the end of a phrase "Carole Sage"~3 will search for "Carole" and "Sage" within 3 words of each other
Target a specific property in my search Use the property name followed by a colon (:) def:google will only search the defendant field and return results that match google as the defendant. See below for a complete list of searchable properties.
Target a specific property with groups of terms Use the property name followed by a colon (:) then group terms together using brackets () def:(google or alphabet)

The fields below are searchable in the Judicial Opinions Library of CasePortal.

Remember to:

  • Put quotations around phrases, or multiple words that you want to match exactly, for example: “employment law”
  • Group keywords and/or phrases in brackets, separated by logical operators, when you want those keywords or phrases to be considered for a single field, for example: def:(“Apple Inc” or Google)
