Instead of `log' I was using `sqrt' imagine. But I needed `log'. Thanks for lively help from Sweden. I have now improved the function which I wanted. It generates SQL query based on the number of C-u prefixes. It is useful when I need to find both "⟦" and "wrs-latest-pages" and "'(" in the text or other multiple terms. (defun hyperscope-by-text-query (&optional prefix query) "Search `hyobjects_text' column for QUERY. User may invoke C-u PREFIX for multiple queries to be searched in the text." (interactive "p") (let* ((times (if (= prefix 1) 1 (log prefix 4))) (query (or query (rcd-ask-times times "Hyperscope query: "))) (query (mapcar 'nil-blank-string query)) (query (delq nil query))) (when query (let* ((sql-query (mapconcat (lambda (i) (format " hyobjects_text ~* %s " (sql-escape-string i))) query " AND ")) (id-list (rcd-sql-list (format "SELECT hyobjects_id FROM hyobjects WHERE %s ORDER BY hyobjects_id DESC" sql-query) hs-db))) (hyperscope nil nil nil nil nil id-list))))) -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns In support of Richard M.
