38 * This file contains various searching-related routines. These fall into
40 * 1. string searches (for /, ?, n, and N)
41 * 2. character searches within a single line (for f, F, t, T, etc)
42 * 3. "other" kinds of searches like the '%' command, and 'word' searches.
48 * The string search functions are divided into two levels:
49 * lowest: searchit(); uses an pos_T for starting position and found match.
50 * Highest: do_search(); uses curwin->w_cursor; calls searchit().
52 * The last search pattern is remembered for repeating the same search.
53 * This pattern is shared between the :g, :s, ? and / commands.
54 * This is in search_regcomp().
56 * The actual string matching is done using a heavily modified version of
57 * Henry Spencer's regular expression library. See regexp.c.
