As per the release notes, 7.15 Beta 2 adds some new search extensions that can be used in the Library. These extensions have the potential to make denomination and commentary collections much faster and more accurate.
For example, I'll take the Expository Commentaries collection rule from https://community.logos.com/forums/t/88829.aspx.
This is the original rule from that post:
type:bible-commentary (series:("3:16 Bible Commentary Series", "Africa Bible Commentary Series", "An Exposition of Ephesians", "An Exposition on Prayer in the Bible", "Analytical Bible Expositor", "Anglican Association of Biblical Scholars Study Series", "Barnes’ Notes on the Old and New Testaments", "Belief: A Theological Commentary on the Bible", "Boice’s Expositional Commentary", "Cecil Sherman Formations Commentary Series", "Clear Study Series", "Daily Study Bible Series", "David Guzik’s Commentaries on the Bible", "Dietrich Bonhoeffer Works", "Discovering Christ", "Essential Bible Companion Series", "Every Christian's Library", "Exploring the Bible Commentary", "Expositions of Holy Scripture (MacLaren)", "Expositor’s Bible", "Feasting on the Word", "Focus on the Bible Commentary", "Following God Workbooks", "For Everyone Bible Study Guides", "Gaebelein Selected Works", "Gaebelein’s Gospel of Matthew", "Gleanings (AW Pink)", "God’s Word for You", "Gromacki Expositions", "High Definition Commentary Series", "Holman New Testament Commentary", "Horae Homileticae", "J. C. Ryle Collection", "Knowing the Bible", "Life Application Bible Commentary", "MacArthur New Testament Commentary", "Manna in the House: or, Daily Expositions of the Gospels", "Old Testament for Everyone", "Opening Up Commentary", "Poor Man’s New Testament Commentary", "Poor Man’s Old Testament Commentary", "Preaching the Word", "R.

Sproul Exposition Collection", "Reformed Expository Commentary", "Romans: Donald Grey Barnhouse", "Roy Gingrich’s Commentaries in Outline Form", "Roy Gingrich’s Commentaries in Outline Form: Bible Themes", "Spurgeon Commentary Series", "St. Andrew’s Expositional Commentary", "Standard Bible Studies", "Studies in the Book of Acts", "Summarized Bible", "Swindoll’s New Testament Insights", "Teach the Bible", "Teacher’s Bible Commentary Series", "Teed Commentary", "The Church Pulpit Commentary", "The Gospel according to the Old Testament", "The Lectionary Commentary", "The Life and Times of Gideon", "The Navarre Bible", "The New Daily Study Bible", "The Orthodox Bible Study Companion", "The Sermon Outline Bible", "Thru the Bible Commentary", "Transformative Word", "Treasury of David", "Walking with Jesus", "Welwyn Commentary Series", "Wiersbe’s Be Series", "Wiersbe’s Expository Outlines", "Works of H.A. Ironside", "Works of John Bunyan"), author:("Blanchard, John", "Chambers, Oswald", "Pink, Arthur Walkington"), mytag:commentary-expository) -series:("Expositor's Bible Commentary")
This is an updated rule that uses the new extensions:
type:bible-commentary ({Series "3:16 Bible Commentary Series", "Africa Bible Commentary Series", "An Exposition of Ephesians", "An Exposition on Prayer in the Bible", "Analytical Bible Expositor", "Anglican Association of Biblical Scholars Study Series", "Barnes’ Notes on the Old and New Testaments", "Belief: A Theological Commentary on the Bible", "Boice’s Expositional Commentary", "Cecil Sherman Formations Commentary Series", "Clear Study Series", "Daily Study Bible Series", "David Guzik’s Commentaries on the Bible", "Dietrich Bonhoeffer Works", "Discovering Christ", "Essential Bible Companion Series", "Every Christian’s Library", "Exploring the Bible Commentary", "Expositions of Holy Scripture (MacLaren)", "Expositor’s Bible", "The Expositor’s Bible", "Feasting on the Word", "A Feasting on the Word Commentary", "Focus on the Bible Commentary", "Following God Workbooks", "For Everyone Bible Study Guides", "Gaebelein Selected Works", "Gaebelein’s Gospel of Matthew", "Gleanings (AW Pink)", "God’s Word for You", "Gromacki Expositions", "High Definition Commentary Series", "Holman New Testament Commentary", "Horae Homileticae", "J. C. Ryle Collection", "Knowing the Bible", "Life Application Bible Commentary", "MacArthur New Testament Commentary", "Manna in the House: or, Daily Expositions of the Gospels", "Old Testament for Everyone", "Opening Up Commentary", "Poor Man’s New Testament Commentary", "Poor Man’s Old Testament Commentary", "Preaching the Word", "R.

Sproul Exposition Collection", "Reformed Expository Commentary", "Romans: Donald Grey Barnhouse", "Roy Gingrich’s Commentaries in Outline Form", "Roy Gingrich’s Commentaries in Outline Form: Bible Themes", "Spurgeon Commentary Series", "St. Andrew’s Expositional Commentary", "Standard Bible Studies", "Studies in the Book of Acts", "Summarized Bible", "Swindoll’s New Testament Insights", "Teach the Bible", "Teacher’s Bible Commentary Series", "Teed Commentary", "The Church Pulpit Commentary", "The Gospel according to the Old Testament", "The Lectionary Commentary", "The Life and Times of Gideon", "The Navarre Bible", "The New Daily Study Bible", "The Orthodox Bible Study Companion", "The Sermon Outline Bible", "Thru the Bible Commentary", "Transformative Word", "Treasury of David", "Walking with Jesus", "Welwyn Commentary Series", "Wiersbe’s “Be” Series", "Wiersbe’s Expository Outlines", "Works of H.A. Ironside", "Works of John Bunyan"}, {Author "Blanchard, John", "Chambers, Oswald", "Pink, Arthur Walkington"}, {MyTag "commentary-expository"})
On my computer, the first rule takes four seconds to run, but the second takes 200ms (20× faster).
N.B. the new syntax is extremely precise and only performs exact matches. For example {Series "Expositor’s Bible"} will only match Expositor’s Bible but not The Expositor’s Bible; but series:"Expositors Bible" will match both as well as Expositor’s Bible Commentary. The first rule had to have a special "-series" term to exclude that last series, which is unnecessary when using {Series}.
