I created a grammar database file with Sherlock Holmes novels/shorts to test the new grammar search tool. All texts are in public domain, so there shouldn't be any copyright issue, but if there is, I'll take it down.
Sample Grammar Database (Sherlock Holmes novels) (On Google Drive) [updated for CasualConc 3.5]
The database is probably too small to enjoy full experience of the tool, but you should be able to taste what it is like. To use the file, unzip it and drag&drop the file on to the top left table in File view in Advanced Grammar mode.
This version is for users of older macOS (prior to Big Sur). There would be no update, but if you find serious problems, please report them to me. I'll try to fix them as much as I can.
