Fix hyphenated tokens in FTS5 lex queries#463
Merged
Conversation
Hyphenated terms like multi-agent, DEC-0054, gpt-4 were being stripped
of hyphens and concatenated (e.g., "multiagent") which missed matches.
Now they're split into FTS5 phrase queries ("multi agent") so the porter
tokenizer matches them correctly.
