This looks implemented on current main by the later session_search redesign. Automated hermes-sweeper review.

Evidence:

• PR fix(session-search): ignore FTS operators when centering excerpts #18690 fixes the old _truncate_around_matches() excerpt-centering helper by filtering FTS5 boolean operators before splitting query terms, but that helper/path is no longer present in the current tracked tools/session_search_tool.py / related session-search files.
• Current discovery now calls db.search_messages(...) in tools/session_search_tool.py:405, then anchors the returned context with db.get_anchored_view(hit_sid, msg_id, ...) in tools/session_search_tool.py:453.
• hermes_state.py:2526 implements get_anchored_view(...) on top of get_messages_around(session_id, around_message_id, ...), so the returned window is centered on the actual matched message id, not whitespace-split query terms such as OR.
• The redesign landed in abf1af540193c30047ff3e7e759c330faf3a880f (feat(session_search): single-shape tool with discovery, scroll, browse — no LLM (#27590)), which is contained in v2026.5.28.
• The linked issue Session search truncation treats FTS5 boolean operators as search terms #4238 was already closed with the same implementation evidence.
