+" File:         IndexedSearch.vim
+" Author:       Yakov Lerner <[email protected]>
+" URL:          http://www.vim.org/scripts/script.php?script_id=1682
+" Last change:  2006-11-21
+"
+" This script redefines 6 search commands (/,?,n,N,*,#). At each search,
+" it shows at which match number you are, and the total number 
+" of matches, like this: "At Nth match out of M". This is printed
+" at the bottom line at every n,N,/,?,*,# search command, automatically.
+"
+" To try out the plugin, source it and play with N,n,*,#,/,? commands.
+" At the bottom line, you'll see wha it shows. There are no new 
+" commands and no new behavior to learn. Just additional info
+" on the bottom line, whenever you perform search.
+"
+" Works on vim6 and vim7. On very large files, won't cause slowdown 
+" because it checks the file size.
+" Don't use if you're sensitive to one of its components :-)
+"
+" I am posting this plugin because I find it useful.
+" -----------------------------------------------------
+" Checking Where You Are with respect to Search Matches
+" .....................................................
+" You can press \\ or \/ (that's backslach then slash), 
+" or :ShowSearchIndex to show at which match index you are,
+" without moving cursor.
+"
+" If cursor is exactly on the match, the message is: 
+"     At Nth match of M
+" If cursor is between matches, following messages are displayed:
+"     Betwen matches 189-190 of 300
+"     Before first match, of 300
+"     After last match, of 300
+" ------------------------------------------------------
+" To disable colors for messages, set 'let g:indexed_search_colors=0'.
+" ------------------------------------------------------
+" Performance. Plugin bypasses match counting when it would take
+" too much time (too many matches, too large file). You can
+" tune performance limits below, after comment "Performance tuning limits"
+" ------------------------------------------------------
+" In case of bugs and wishes, please email: iler.ml at gmail.com

+" Last changes
+" 2006-10-20 added limitation by # of matches
+" 061021 lerner fixed problem with cmap <enter> that screwed maps 
+" 061021 colors added
+" 061022 fixed g/ when too many matches
+" 061106 got message to work with check for largefile right
+" 061110 addition of DelayedEcho(ScheduledEcho) fixes and simplifies things
+" 061110 mapping for nN*# greately simplifified by switching to ScheduledEcho
+" 061110 fixed problem with i<c-o>/pat<cr> and c/PATTERN<CR> Markus Braun
+" 061110 fixed bug in / and ?, Counting moved to Delayd
+" 061110 fixed bug extra line+enter prompt in [/?] by addinf redraw
+" 061110 fixed overwriting builtin errmsg with ">1000 matches"
+" 061111 fixed bug with gg & 'set nosol' (gg->gg0)
+" 061113 fixed mysterious eschewing of @/ wfte *,#
+" 061113 fixed counting of match at the very beginning of file
+" 061113 added msgs "Before single match", "After single match"
+" 061113 fixed bug with &ut not always restored. This could happen if
+"        ScheduleEcho() was called twice in a row.
+" 061114 fixed problem with **#n. Direction of the last n is incorrect (must be backward
+"              but was incorrectly forward)
+" 061114 fixed disappearrance of "Hit BOTTOM" native msg when file<max and numhits>max
+" 061116 changed hlgroup os "At last match" from DiffChange to LineNr. Looks more natural.
+" 061120 shortened text messages.
+" 061120 made to work on vim6
+" 061120 bugfix for vim6 (virtcol() not col())
+" 061120 another bug with virtcol() vs col()
+" 061120 fixed [/?] on vim6 (vim6 doesn't have getcmdtype())
+" 061121 fixed mapping in <cr> with supertab.vim. Switched to [/?] mapping, removed <cr> mapping.
+"        also shortened code considerably, made vim6 and vim7 work same way, removed need
+"        for getcmdtype().
+" 061121 fixed handling of g:indexed_search_colors (Markus Braun)
+
+
+" Wishlist
+" -  using high-precision timer of vim7, count number of millisec
+"    to run the counters, and base auto-disabling on time it takes.
+"    very complex regexes can be terribly slow even of files like 'man bash'
+"    which is mere 5k lines long. Also when there are >10k matches in the file
+"    set limit to 200 millisec
+" - implement CursorHold bg counting to which too_slow will resort
+" - even on large files, we can show "At last match", "After last match"
+" - define global vars for all highlights, with defaults
