BAILII is now using the Lucy search library.

This requires some minor changes to the search syntax. There is no longer a search method dropdown ("all these words", "this phrase", etc.); instead you can group multiple search terms within your query. For example:

• customary recreation right, or customary AND recreation AND right, finds documents containing all of the terms "customary", "recreation" and "right". (Also "customarily", "recreational", etc.; all search terms are stemmed.)
• alien OR immigrant finds documents containing either or both of the terms "alien" or "immigrant".
• "customary right" finds documents containing that phrase.
• title:Locabail finds documents containing "Locabail" in the title.
• If you want an exact word or phrase match, ignoring stemming of search terms, use the exact: search operator: exact:(customary AND recreation) will find documents containing those two specific words, but not "customarily", "recreational" etc.

More complex queries are also possible, with optional parentheses:

• (alien OR immigrant) AND title:Locabail AND NOT "customary right"
• title:Police AND Lynch (only the first word is in the title)
• title:(Police AND Lynch) (both words are in the title)
